Abstract
Cholinephosphate cytidylyltransferase (CTP : cholinephosphate cytidylyltransferase, EC 2.7.7.15) is located in both the microsomal and supernatant fractions of adult lung when the tissue is homogenized in 0.145 M NaCl. The activity is located predominantly in the supernatant fraction in fetal lung. Cholinephosphate cytidylyltransferase in the supernatant from fetal lung is stimulated 4- to 6-fold by the additions of total lung lipid. Serine phosphoglycerides and inositol phosphoglycerides specifically caused stimulation whereas choline phosphoglycerides and ethanolamine phosphoglycerides produced no stimulation. Lysophosphatidylcholine cause some stimulation, but only at high concentrations. A number of detergents were investigated. All produced inhibition except for the ampholytic detergent, miranol H2M which was not inhibitory. None of the detergents produced any stimulation of activity. Cytidylyltransferase activity in fetal lung when assayed in the absence of lipid is about 25% of the adult. The activity when assayed in the presence of lipid is equal or slightly higher than adult levels. The activity, measured without added phospholipid, increases 5- to 6-fold within 12 h after birth, to values higher than in the adult. The activity, measured in the presence of phospholipid, increased almost linearly from -2 day until +1 day. There is an inverse relationship between the concentration of phospholipid in the fetal lung supernatant and the degree of lipid stimulation. Chromatographic experiments with Biogel A 1.5 columns have shown that cytidylyltransferase can exist in two molecular sizes, a small molecular size that requires phospholipid for activity, and a larger molecular weight species which does not require the addition of phospholipid for activity. Fetal lung has a higher proportion of the low molecular weight form than adult lung. The small molecular weight species can be converted to the larger molecular weight form by the addition of phospholipids.

Abstract
An isolated lung ventilated with pulses of negative pressure and perfused through the pulmonary vasculature was utilized for the study of 3-sn-phosphatidylcholine synthesis. The perfusion fluid consisted of a Krebs-Ringer phosphate buffer with 6% bovine serum albumin, pH 7.4, and the appropriate substrate. The simultaneous incorporation of (1-14C) palmitate and (2-3H) glycerol and the simultaneous incorporation of (CH3-14C) choline and (CH3-3H) methionine were examined. From these experiments it is concluded: 1) lung tissue incorporates (2-3H) glycerol into 3-sn-phosphatidylcholine to a greater extent than any other lipid examined; 2) both choline and methionine contribute to the synthesis of 3-sn-phosphatidylcholine, and 50-70% of the label in its nitrogen base is derived from choline and 30-50% from methionine; and 3) a high PO2 appears to reduce the synthesis of 3-sn-phosphatidylcholine.

Abstract
The incorporation of L-serine-U-14C, L-serine-3-14C, and D,L-serine-1-14-C into the glycerophospholipids of rat liver in vivo was determined over a period of 3 min to 13 hr following intravenous injection. The radioactivity from these serines was transferred to variable extent into the glycerol, fatty acid, and nitrogenous base parts of all the glycerophospholipids and neutral lipids. The half-lives and turnover rates of phosphatidylserine calculated from the precursor-product specific activity curves obtained with L-serine-U-14C were 14 min and 0.28 mumol/min/liver, respectively. The half-lives and turnover rates of phosphatidylserine as measured from the decay data of lipid serine from all markers averaged, respectively, 8.2 hr and 0.0008 mumol/min/liver. The discrepancy between these turnover rates was attributed to an understimation of degradation of phosphatidylserine due to its continued biosynthesis and/or an extensive reutilization of L-serine. By monitoring the formation of radioactive lipid ethanolamine, it was found that phosphatidylserine was decarboxylated at one-half the rate of lipid serine biosynthesis. It is suggested that as much as one-half of total phosphatidylserine may be degraded by other mechanisms, such as base exchange with choline, ethanolamine, and serine, as already demonstrated in vitro by other workers. The time course and nature of labeling of phosphatidylcholine was consistent with an extensive conversion of radioactive L-serine to 1-carbon fragments and a rapid methylation of phosphatidylethanolamine to phosphatidylcholine.

Abstract
The relative importance of the choline incorporation and methylation pathways of phosphatidylcholine biosynthesis was studied in the rat, rabbit, rhesus monkey and human lung. In vitro studies showed that phosphatidylethanolamine methyltransferase activity in the lungs of all species was only a fraction of that in rat liver. In vivo experiments were carried out to study the incorporation of an intravenously administered equimolar mixture of L-[methyl-14C]-methionine and [methyl-3H] choline into lipid inthe lung and liver of the rabbit and monkey. Over 90% of the total radioactivity incorporated into lipid was found in phosphatidylcholine. In the liver, methionine incorporation was 40--71% of that of choline in the rabbit and 99--120% in the monkey while in the lungs of both species it was less than 3%. On a weight basis, choline incorporation in the lung was 2--4 times that in the liver. These findings suggest that the methylation pathway is of little quantitative significance in the biosynthesis of phosphatidylcholine in primate and non-primate lung.

Abstract
1. The phosphonium analogues of choline, phosphorylcholine, CDPcholine and phosphatidylcholine were synthesized chemically and characterized by 1H-NMR and 31P-NMR; in 1,2-distearoyl-DL-glycero-3-phosphorylphosphocholine, the 31P-NMR chemical shift of phosphonium relative to phosphate was--28.2 ppm. 2. A comparison was made of the rates of reaction of choline kinase, cholinephosphate cytidyltransferase, cholinephosphotransferase and phospholipase C on natural and phosphonium substrates. Enzyme reaction rates were similar for all but the cytidyltransferase, which exhibited a 3-fold preference for the normal substrate. 3. Weanling rats were maintained for 6 weeks on a diet in which choline was fully replaced by phospho[1,2-14C2]choline mixed with a trace of [Me-3H] choline. Incorporation of phosphocholine into liver lipids was detectable by 31P-NMR even in crude tissue homogenates. Choline-based phospholipids of liver, kidney, lung and brain were extracted, and phosphocholine incorporation calculated from 31P-NMR peak area ratios. The phosphatidylcholine analogues were separated by preparative thin-layer chromatography. Incorporation of phosphocholine ranged from 33% in lung phosphatidylcholine to 6% in kidney sphingomyelin. Variations in 14C/3H ratio between feed and phospholipid extracts indicated preferences for exogenous choline over phosphocholine varying from 1.3: 1 in brain to 3.2: 1 in liver. The results indicated that phosphocholine is a potentially useful 31P-NMR probe for the study of membrane lipids.

Abstract
Radioactivity from intraperitoneally or intraportally injected 1-acyl-snglycero-3-phosphorylcholine, doubly labelled in either palmitoyl, glycerol or phosphoryl moities, was incorporated largely into disaturated or mixed disaturated-oligoenoic fractions of phosphatidylcholine in guinea pig liver. In rat liver the tetraenoic class was the most highly labelled and only very low radioactivity was recovered from disaturated or monoenoic species. The methylation of phosphatidylethanolamine to phosphatidylcholine, as judged by the incorporation of intraperitoneally injected L-[Me-14 C] methionine, involved selectively tetraenoic and polyenoic (greater than 4 double bonds) classes in rat liver. In guinea pig liver, methylation activity was much lower and led to the formation principally of dienoic classes of phosphatidylcholine. These experiments confirm the work of others that in rat liver, which has a high level of polyunsaturated classes of phosphatidylcholine, the "indirect" pathways of synthesis give rise chiefly to these classes. However, the priorties in guinea pig liver are different, since the levels of polyunsaturated classes are much lower, and although the "indirect" pathways of synthesis are operative they are directed mainly toward the formation of more saturated classes.

Abstract
Lipid droplets isolated from rabbit renal medullary tissue were analyzed and found to be composed of triglyceride and free fatty acids in a ratio of 2.9:1. These triglycerides were unique when compared to triglycerides of other rabbit tissues examined, in that they contained high percentages of octadecanoic acid (stearic acid, 9.8%), 5,8,11,14-eicosatetraenoic acid (arachidonic acid, 6.8%), and 7,10,13,16-docosatetraenoic acid (adrenic acid, 10%). Lipid droplet triglycerides were found to increase during experimental hydronephrosis and after administration of indomethacin, a prostaglandin synthetase and phosphodiesterase inhibitor. From gas liquid chromatography of fatty acid methyl esters of these triglycerides, it was determined that they were enriched further in their percent composition of 9,12-octadecadienoic acid (linoleic acid) and arachidonic acid, a prostaglandin precursor. The inverse relationship between lipid droplets and prostaglandin content in the inner medulla suggested a significant role of lipid droplet triglycerides as storage pools for prostaglandin precursors.

Abstract
1. The phospholipid composition of Fasciola hepatica, the common liver fluke, was compared to that of the liver of the host animals (rats and cattle). Considerable differences were found:monoacyl-sn-glycero-3-phosphorylcholine, hardly detectable in the liver, was found in significant amounts in the parasite. On the other hand, sphingomyelin, a normal constituent in the liver, appears to be absent in the liver fluke. Fasciola hepatica isolated from rat and cow liver had a strikingly similar phospholipid composition. 2. Qualitative and quantitative differences were also found between the fatty acyl constituents of the phospholipids of the parasite and the liver. The major difference was the presence of eicosaenoic and eicosadienoic acids in the parasite, whereas these acids were not detected in the liver. 3. In vitro incubations of Fasciola hepatica in the presence of (32P)phosphate and (2-3H)glycerol resulted in the labelling of all phospholipids of the parasite, except that the 3H label did not incorporate into ethanolamine plasmalogen. This is in agreement with the concept that in animals, glycerol is introduced into plasmalogens via dihydroxyacetonephosphate. 4. Homogenates of liver flukes were found to catalyze the synthesis of phosphatidylcholine from 1,2-diacyl-sn-glycerols and CDPcholine. 5. These results strongly suggest that Fasciola hepatica is capable of synthesizing at least part of its fatty acids and phospholipids.

Abstract
The phospholipid composition from various organs of the fresh water eel, such as gill, kidney, gut, liver and muscle, were determined by thin-layer chromatography. The major phosphatides found in these tissues were PC, PE and SPH and minor constituents PS, PI, DPG, AP and also LPC in the gut. A greater percentage of PS and SPH occurs in the osmoregulatory effector organs such as gill, kidney, and gut. From in vivo comparative kinetic studies of the 32P incorporation into the phospholipids, between 6 and 48 hours, certain remarkable features of phospholipid metabolism have been found in these tissues. A low uptake of inorganic 32P into the tissue lipid phosphorus was observed in the eel at 15 degrees C. The specific activity of the lipid phosphorus increased continuously in all tissues during 48 hours after 32P injection. During this experimental period, phosphatidic acid and phosphatidyl inositol fractions were labelled most rapidly in gill, kidney and gut, while the specific activity of the phosphatidyl choline fraction remained low in these organs. In liver, the rate of PC formation appears to be faster than the PI and PE biosynthesis. In gill and gut, the PE showed greater turnover than the PC as measured by 32P incorporation. In the eel, an euryhalin fish, the DPG of osmoregulatory effector organs has a high specific activity at all times. PS showed only a high specific activity in the gill. Labelling of SPH occured slowly in the various tissues only becoming evident after 24 hours. The results are compared with those published for other poikilotherm and homeotherm vertebrates. Relative differences between the turnover of various tissue phosphatides are discussed with of reference to the general scheme on phospholipid biosynthesis and to the physiological functions of the various organs.

Abstract
Effects of orotic acid on liver lipid accumulation and incorporation of methionine [methyl-14C] into liver phosphatidylcholine and protein, and into serum beta-lipoprotein were studied. Male and female rats of Wistar strain were fed a semisynthetic diet supplemented with 1 per cent orotic acid for 7 days. Feeding of orotic acid induced a marked fatty liver in female rats, but not in males. In female rats, radioactivity in liver phosphatidylcholine was significantly decreased by orotic acid, and that in liver protein was slightly decreased. In male rats, incorporation of methionine [methyl-14C] into liver phosphatidylcholine and protein was unchanged between the control and the rats fed orotic acid. Radioactivity in serum beta-lipoprotein was decreased to a greater extent in female rats than in males. These results suggest that sex difference in the development of fatty liver may be due to the difference in the effect of orotic acid on liver phosphatidylcholine biosynthesis.

Abstract
Pregnant Long-Evans rats were subjected to a teratogenic regimen, i.e., were fed a synthetic diet lacking folic acid and containing 9-methylpteroylglutamic acid on the 11th to 14th days of gestation. Experimental and control pregnant rats injected with 10 muCi of [2-14C] ethanolamine on the 14th day were killed 1 or 2 days later. The total radioactivity and radioactivities of phosphatidylethanolamine (PE), phosphatidylcholine (PC), and lysophosphatidylethanolamine (LPE) were determined in chloroform extracts of homogenates and subcellular fractions prepared from hemochorionic and yolk sac placentas and maternal liver. The distribution of radioisotope into PC and PE of control and experimental yolk sac placentas was similar, and paralleled the distribution in maternal liver. However, the distribution of radioisotope into PC and PE of the hemochorionic placentas did not parallel that of the maternal liver, and radiolabeled PC accumulated faster in experimental placentas than in controls. We suggest that the ability of the hemochorionic placenta to synthesize PC from PE was impaired by the teratogenic regimen, and that the organ took up relatively more PC from the maternal plasma. We propose that this teratogen-induced shift from placental lecithin synthesis to selective lecithin uptake underlies the previous finding of an increased accumulation of radio-labeled PC in embryos from pregnant females subjected to this teratogenic regimen (Chepenik and Waite, '73).

Portions of lung from 25 human foetuses between 12 and 26 wk of gestational age were examined for ultrastructural changes during maturation of the epithelial cells. In 10 cases type I pneumocytes and in five cases type II cells were differentiated. The changes associated with the formation of lamellar inclusion bodies in type II cells are described. It is concluded that this is a synthetic process in which protein and lipid assembly are important. Changes in glycogen and participation of dense bodies are striking.

Abstract
The effects of halide ions on several pathways of lipid metabolism have been investigated in rat liver slices. Through the use of carboxyl-14-C-labeled acetate and palmitate and U-14-C-labeled glycine, striking differences were found when the effects of the four halide ions on the labeling of the lipids were compared. Both fluoride and iodide dpressed [14-C]acetate incorporation into phosphatide and triglyceride fractions. The effects of the halide ions on the labeling from the effects observed when [14-C]acetate was the precursor of the lipid molecule. In contrast with the phospholipid fractions, the level of radioactivity from [14-C]palmitate incorporated into the triglycerides was lower with fluoride than with chloride. The incorporation of [14-C]glycine into the phospholipids was also greatly depressed by fluoride. The effects of halide ions on acetoacetate formation, on 14-CO2 production and on the acetylcoenzyme A synthetase of rat liver were also investigated. Decreasing [I-14-C]-acetate conversion to acetoacetate iodide had an opposite effect on 14-CO2 production from the same labeled substrate. The effects of the four halide ions and the differences observed with the three labeled substrates on several pathways related to lipid metabolism are discussed.
