Abstract
BACKGROUND Diacylglycerols as a fat substitute in meat products is a growing area of interest. This study was conducted to analyze the digestion rate, digestion extent, and changes in interfacial properties of lard, glycerolized lard (GL), and purified GL (PGL) in an emulsions system by pH-stat in vitro digestion. RESULTS PGL had significantly higher hydrolysis rate and final digestion extent than lard (P ≤ 0.05) during in vitro digestion. The analysis on diameter variations of lard, GL, and PGL during digestion indicated that the surface- and volume-weighted mean particle diameters of all samples had the same variation trend, but variation degree was different. Concurrently, the ζ-potential analysis of the lard, GL, and PGL during the digestion process showed that the absolute values of the ζ-potentials of the three types of lipids increased at first and subsequently decreased. The microstructure changes results for lard, GL, and PGL showed there was no obvious flocculation, and the particle size of lard throughout the digestion process was larger than that of GL and PGL. CONCLUSION This study showed that lard-based diacylglycerols had high digestibility characteristics and could be applied as a functional lipid in meat products to improve human health. © 2020 Society of Chemical Industry.

Abstract
This study aimed to characterize the chemical composition and antioxidant activity of the oil and the methanolic extract of Myrtus communis var. baetica seed. The oil yield of myrtle seed was 8.90%, with the amount of neutral lipid, especially triacylglycerol, being the highest, followed by phospholipids and glycolipids. Total lipids and all lipid classes were rich in linoleic acid. The content of total phenols, flavonoids, tannins, and proanthocyanidins of the methanolic extract and the oil from myrtle seed was determined using spectrophotometric methods. Antioxidant activities of the oil and the methanolic extract from myrtle seed were evaluated using 1,1-diphenyl-2-picrylhydrazyl radical scavenging, β-carotene-linoleic acid bleaching, and reducing power and metal chelating activity assays. In all tests, the methanolic extract of myrtle seed showed better antioxidant activity than oil. This investigation could suggest the use of myrtle seed in food, industrial, and biomedical applications for its potential metabolites and antioxidant abilities.

Abstract
Biochemical events involved in the acquisition of germinability and storability during orthodox seed development are well documented; however, the roles played by the physical organization of lipids and water are poorly characterized. The aim of this work was to determine, using a thermodynamic approach, whether changes in thermal properties of lipid reserves, and intracellular glasses might play a role in sunflower (Helianthus annuus L.) seed development. Triacyglycerols (TAGs) accumulated in cotyledons until the end of seed filling, which occurred 42 days after anthesis (DAA). Further seed development, leading to mature seed at 58 DAA, was mainly associated with an enlargement of lipid bodies without significant changes either in the lipid content or in their composition. When cooled to -100 degrees C, lipid reserves from cotyledons of mature seeds displayed alpha and beta' polymorphic crystalline structures; however, the ability to form alpha crystals, which was an indicator of lipid purity, progressively appeared during seed development. Characteristics of lipid melting confirmed that seed maturation drying was associated with changes in TAG physical organization. Cotyledon development was associated with an increase in the temperature of glass to rubber transition (Tg), thus suggesting a decrease in molecular mobility during maturation drying. This phenomenon was concomitant with an increase in raffinose content. Our results demonstrate that physical characteristics of lipid reserves and glasses of sunflower cotyledons are developmentally regulated and might play a role in acquisition of seed germinability and storability.

Abstract
Sorgoleone, 2-hydroxy-5-methoxy-3-[(8'Z,11'Z)-8',11',14'-pentadecatriene]-p-benzoquinone (1), and its corresponding hydroquinone are the major components of the root exudate of Sorghum bicolor. The name sorgoleone includes minor analogues differing in the length or degree of unsaturation of the 3-alkyl side chain. These compounds are known to be phytotoxic, probably through inhibition of photosystem II (PSII) driven oxygen evolution, as previously demonstrated for 1. Isolation of these sorgoleone congeners was achieved by C(8) column chromatography and argentation thin-layer chromatography, and the purified compounds were structurally characterized. The abilities of the minor sorgoleones to inhibit PSII were similar to that of the major compound, suggesting that all of these sorgoleone congeners contribute to the overall allelopathy of sorghum.

Abstract
The effects of diets containing equal amounts of alpha (alpha)- or gamma (gamma)-linolenic acid on lipid metabolism were compared in rats. Four groups of male Wistar rats were given the diets containing 20% perilla/corn mixed oil or borage oil in the absence (PO- and BO-diets, respectively) or presence (CPO- and CBO-diets) of cholesterol for 20 days. The PO-diet yielded lower serum cholesterol than the BO-diet, although the difference was not observed between the CPO and CBO groups. The PO and CPO groups showed lower high-density lipoprotein cholesterol than the BO and CBO groups, respectively. A similar tendency was observed in serum phospholipids. The CPO-diet gave markedly lower hepatic triglycerides than the CBO-diet. The activity of hepatic 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase was much lower on the PO-diet than on the BO-diet. mRNA abundance of HMG-CoA reductase was lower in rats on the PO-diet than on the BO-diet, though there was no significant difference between the CPO and CBO groups. The present results indicate that alpha-linolenic acid exhibits a larger hypocholesterolemic effect than gamma-linolenic acid, and it may be displayed mainly through the repression of the activity and mRNA expression of HMG-CoA reductase.

Abstract
Diets high in linoleic acid (20% safflower oil contained 77.3% linoleic acid, SO-diet) and alpha-linolenic acid (20% perilla oil contained 58.4% alpha-linolenic acid, PO-diet) were fed to rats for 3, 7, 20, and 50 days, and effects of the diets on lipid metabolism were compared. Levels of serum total cholesterol and phospholipids in the rats fed the PO-diet were markedly lower than those fed the SO-diet after the seventh day. In serum and hepatic phosphatidylcholine and phosphatidylethanolamine, the proportion of n-3 fatty acids showed a greater increase in the PO group than in the SO group in the respective feeding-term. At the third and seventh days after the commencement of feeding the experimental diets, expressions of hepatic 3-hydroxy-3-methylglutaryl coenzyme A reductase mRNA were significantly higher in the SO group than those in the PO group, although the difference was not observed in the longer term. There were no significant differences in the LDL receptor mRNA levels between the two groups through the experimental term, except 3-days feeding. These results indicate that alpha-linolenic acid has a more potent serum cholesterol-lowering ability than linoleic acid both in short and long feeding-terms.

Abstract
Cadmium and copper uptake and distribution, as well as their effects on growth and lipid composition were investigated in 17-day-old tomato seedlings (Lycopersicon esculentum Mill. cv. 63/5 F1) grown in culture solution supplied with two concentrations of Cd or Cu (0, 5 and 50 microM). The accumulation of Cd and Cu increased with external metal concentrations, and was considerably higher in roots than in primary leaves. Biomass production of the growing roots and primary leaves was strongly depressed at high metal levels. Also, significant decreases in the content of lipid classes and changes of fatty acid composition were recorded in heavy metal-stressed plants in comparison with controls. Glycolipid contents were decreased more in leaves than in roots by Cd-treatment, but copper decreased both to similar extents in both organs. Likewise, both metals reduced the phospholipid and neutral lipid contents more in roots than in leaves. In almost all lipid classes the proportion of palmitic acid (16:0) increased, and that of linoleic (18:2) or linolenic (18:3) acid decreased, suggesting that heavy metal treatment induced an alteration in the fatty acid desaturation processes. Furthermore, the accumulation of palmitate (16:0) rather than stearate (18:0) indicated an alteration in the ratio of products from the fatty acid synthase. Copper was found to be the most unfavourable for plant growth and lipid metabolism. The possible mechanisms by which heavy metals, especially Cu, induce a strong lipid shift are discussed.

Abstract
Chronic cold exposure of rats (9 days at 5 degrees C) induces an alteration of the fatty acid composition of phospholipids in brown adipose tissue. The alteration is due to an increase of the unsaturation degree of these lipids. The phenomenon can be reproduced by 10(-7) mole. h-1 administration of noradrenaline for 9 days in rats kept at 25 degrees C. Thus, phospholipid alteration in brown fat of cold exposed rats is most probably a consequence of the increase of sympathetic tone which occurs in this tissue during exposure to cold.

Abstract
1. Phospholipids were more intensively labelled from ammonium [1-14C]glycerophosphate in mesosomes than in protoplasts isolated from Bacillus subtilis. 2. When mesosomes, containing phospholipids labelled from sodium-[32P] phosphate were incubated with non radioactive protoplasts, labelled phospholipids were recovered in protoplasts after incubation. 3. This transfer of phospholipids from mesosomes toward protoplasts is time-dependent. 4. Soluble proteins obtained from Bacillus subtilis after ammonium sulphate precipitation were separated on a Sephadex G-100 column. 5. The two main fractions were able to accelerate the transfer of phospholipids from mesosomes toward protoplasts. 6. The first peak stimulated more actively the transfer of phosphatidylethanolamine whereas the second one preferentially accelerated the transfer of phosphatidylglycerol and diphosphatidylglycerol.

Abstract
Childhood coronary sclerosis was studied histologically, histochemically immunohistochemically and biochemically on 60 autopsy cases aged from new-born to 20 years. Intimal thickening often started even in the newborn babies particularly at branching or bending points of the arteries, where fibrocellular proliferation with acid mucopolysaccharide accumulation was the main histological feature. Microthrombi were occasionally demonstrated even in infants, and fatty streaks appeared generally in the second decade. Microthrombi were usually smaller and fewer than fatty streaks. Beta-lipoprotein and fibrinogen infiltrations into intima were proven in some cases. Mural vascularization was occasionally observed especially in the areas beneath intimal thickening. Pressure effect of the blood stream and anatomically specific points in the arteries seemed to be important as initial factors of coronary sclerosis, where plasma constituents might pass in an easier manner into intimas by increased permeability. Secondarily mural capillaries might play some role in developing atheromas which would produce an eccentrically located luminal obstruction later in adulthood, by local circulatory disturbances within the arterial walls.
