Abstract
ω-Phenyl-alkenoic acids are abundant in coffee, fruits, and vegetables. Along with ω-phenyl-alkanoic acids, they are produced from numerous dietary (poly)phenols and aromatic amino acids in vivo. This review addresses how phenyl-ring substitution and flux modulates their gut microbiota and endogenous β-oxidation. 3',5'-Dihydroxy-derivatives (from alkyl-resorcinols, flavanols, proanthocyanidins), and 4'-hydroxy-phenolic acids (from tyrosine, p-coumaric acid, naringenin) are β-oxidation substrates yielding benzoic acids. In contrast, 3',4',5'-tri-substituted-derivatives, 3',4'-dihydroxy-derivatives and 3'-methoxy-4'-hydroxy-derivatives (from coffee, tea, cereals, many fruits and vegetables) are poor β-oxidation substrates with metabolism diverted via gut microbiota dehydroxylation, phenylvalerolactone formation and phase-2 conjugation, possibly a strategy to conserve limited pools of coenzyme A. 4'-Methoxy-derivatives (citrus fruits) or 3',4'-dimethoxy-derivatives (coffee) are susceptible to hepatic "reverse" hydrogenation suggesting incompatibility with enoyl-CoA-hydratase. Gut microbiota-produced 3'-hydroxy-4'-methoxy-derivatives (citrus fruits) and 3'-hydroxy-derivatives (numerous (poly)phenols) are excreted as the phenyl-hydracrylic acid β-oxidation intermediate suggesting incompatibility with hydroxy-acyl-CoA dehydrogenase, albeit with considerable inter-individual variation. Further investigation is required to explain inter-individual variation, factors determining the amino acid to which C6-C3 and C6-C1 metabolites are conjugated, the precise role(s) of l-carnitine, whether glycine might be limiting, and whether phenolic acid-modulation of β-oxidation explains how phenolic acids affect key metabolic conditions, such as fatty liver, carbohydrate metabolism and insulin resistance.

Abstract
Coenzyme A (CoA) is the predominant acyl carrier in mammalian cells and a cofactor that plays a key role in energy and lipid metabolism. CoA and its thioesters (acyl-CoAs) regulate a multitude of metabolic processes at different levels: as substrates, allosteric modulators, and via post-translational modification of histones and other non-histone proteins. Evidence is emerging that synthesis and degradation of CoA are regulated in a manner that enables metabolic flexibility in different subcellular compartments. Degradation of CoA occurs through distinct intra- and extracellular pathways that rely on the activity of specific hydrolases. The pantetheinase enzymes specifically hydrolyze pantetheine to cysteamine and pantothenate, the last step in the extracellular degradation pathway for CoA. This reaction releases pantothenate in the bloodstream, making this CoA precursor available for cellular uptake and de novo CoA synthesis. Intracellular degradation of CoA depends on specific mitochondrial and peroxisomal Nudix hydrolases. These enzymes are also active against a subset of acyl-CoAs and play a key role in the regulation of subcellular (acyl-)CoA pools and CoA-dependent metabolic reactions. The evidence currently available indicates that the extracellular and intracellular (acyl-)CoA degradation pathways are regulated in a coordinated and opposite manner by the nutritional state and maximize the changes in the total intracellular CoA levels that support the metabolic switch between fed and fasted states in organs like the liver. The objective of this review is to update the contribution of these pathways to the regulation of metabolism, physiology and pathology and to highlight the many questions that remain open.

Abstract
Peroxisomes carry out many essential lipid metabolic functions. Nearly all of these functions require that an acyl group-either a fatty acid or the acyl side chain of a steroid derivative-be thioesterified to coenzyme A (CoA) for subsequent reactions to proceed. This thioesterification, or "activation", reaction, catalyzed by enzymes belonging to the acyl-CoA synthetase family, is thus central to cellular lipid metabolism. However, despite our rather thorough understanding of peroxisomal metabolic pathways, surprisingly little is known about the specific peroxisomal acyl-CoA synthetases that participate in these pathways. Of the 26 acyl-CoA synthetases encoded by the human and mouse genomes, only a few have been reported to be peroxisomal, including ACSL4, SLC27A2, and SLC27A4. In this review, we briefly describe the primary peroxisomal lipid metabolic pathways in which fatty acyl-CoAs participate. Then, we examine the evidence for presence and functions of acyl-CoA synthetases in peroxisomes, much of which was obtained before the existence of multiple acyl-CoA synthetase isoenzymes was known. Finally, we discuss the role(s) of peroxisome-specific acyl-CoA synthetase isoforms in lipid metabolism.

Abstract
Triglyceride synthesis in mammalian tissues requires glycerol 3-phosphate as the source of triglyceride glycerol. In this study the relative contribution of glyceroneogenesis and glycolysis to triglyceride glycerol synthesis was quantified in vivo in adipose tissue, skeletal muscle, and liver of the rat in response to a chow diet (controls), 48-h fast, and lipogenic (high sucrose) diet. The rate of glyceroneogenesis was quantified using the tritium ([(3)H(2)]O) labeling of body water, and the contribution of glucose, via glycolysis, was determined using a [U-(14)C]glucose tracer. In epididymal and mesenteric adipose tissue of control rats, glyceroneogenesis accounted for approximately 90% of triglyceride glycerol synthesis. Fasting for 48 h did not alter glyceroneogenesis in adipose tissue, whereas the contribution of glucose was negligible. In response to sucrose feeding, the synthesis of triglyceride glycerol via both glyceroneogenesis and glycolysis nearly doubled (versus controls); however, glyceroneogenesis remained quantitatively higher as compared with the contribution of glucose. Enhancement of triglyceride-fatty acid cycling by epinephrine infusion resulted in a higher rate of glyceroneogenesis in adipose tissue, as compared with controls, whereas the contribution of glucose via glycolysis was not measurable. Glyceroneogenesis provided the majority of triglyceride glycerol in the gastrocnemius and soleus. In the liver the fractional contribution of glyceroneogenesis remained constant (approximately 60%) under all conditions and was higher than that of glucose. Thus, glyceroneogenesis, in contrast to glucose, via glycolysis, is quantitatively the predominant source of triglyceride glycerol in adipose tissue, skeletal muscle, and liver of the rat during fasting and high sucrose feeding.

Abstract
1. In this study we explored the relationship between specific acyl-CoA esters and induction of acyl-CoA binding protein (ACBP) and enzymes related to the proliferation of peroxisomes. Male Wistar rats were administered a single dose (150 mg/day/kg) of sulphur-substituted fatty acid analogues, and the effects of tetradecylthioacetic acid and 3-thiadicarboxylic acid, which both act as peroxisome proliferators, were compared with the effects of tetradecylthiopropionic acid and palmitic acid which do not induce peroxisome proliferation. 2. The hepatic level of total long-chain acyl-CoA was significantly increased within 12 h of feeding these fatty acids, except in rat fed tetradecylthioacetic acid. Hplc chromatograms of liver extracts prepared from rat fed tetradecylthioacetic acid showed that tetradecylthioacetyl-CoA ester accumulated in the liver 4 h after feeding and had disappeared after 24 h. In liver extracts of the tetradecylthiopropionic acid-treated rat tetradecylthiopropionyl-CoA was not observed, but the appearance of a new long-chain acyl-CoA ester, probably a metabolite of tetradecylthiopropionic acid, was detected. This new peak reached a maximum 4h after feeding. In rat fed tetradecylthioacetic acid and 3-thiadicarboxylic acid the hepatic level of fatty acyl-CoA oxidase mRNA increased 8 h after feeding, while the acyl-CoA oxidase activity had increased after 12 h. 3. The early accumulation of specific tetradecylthioacetyl-CoA suggests that this ester may be a possible mediator of the induction of fatty acyl-CoA oxidase. The level of hepatic acyl-CoA binding protein, long-chain acyl-CoA hydrolase activity and long-chain acyl-CoA synthetase activity did not change after a single dose of all four fatty acids. Prolonged administration of 3-thia fatty acids resulted, however, in a dose- and time-dependent increase in hepatic ACBP content and ACBP mRNA level. The amount of ACBP increased in parallel to the long-chain acyl-CoA hydrolase activity. The correlated induction of fatty acyl-CoA binding protein and long-chain acyl-CoA hydrolase seems to be dependent on a sustained accumulation of total long-chain acyl-CoA esters.

Abstract
Data obtained in earlier studies with rats fed diets containing high doses of peroxisome proliferators (niadenate, tiadenol, clofibrate, or nitotinic acid) are used to look for a quantitative relationship between peroxisomal beta-oxidation, palmitoyl-CoA hydrolase, palmitoyl-CoA synthetase and carnitine palmitoyltransferase activities, and the cellular concentration of their substrate and reaction products. The order of the hyperlipidemic drugs with regard to their effect on CoA derivatives and enzyme activities was niadenate greater than tiadenol greater than clofibrate greater than nicotinic acid. Linear regression analysis of long-chain acyl-CoA content versus palmitoyl-CoA hydrolase and peroxisomal beta-oxidation activity showed highly significant linear correlations both in the total liver homogenate and in the peroxisome-enriched fractions. A dose-response curve of tiadenol showed that carnitine palmitoyltransferase and palmitoyl-CoA synthetase activities and the ratio of long-chain acyl-CoA to free CoASH in total homogenate rose at low doses before detectable changes occurred in the peroxisomal beta-oxidation and palmitoyl-CoA hydrolase activity. A plot of this ratio parallelled the palmitoyl-CoA synthetase activity. The specific activity of microsomally localized carnitine palmitoyl-transferase was low and unchanged up to a dose where no enhanced peroxisomal beta-oxidation was observed, but over this dose the activity increased considerably so that the specific of the enzyme in the mitochondrial and microsomal fractions became comparable. The mitochondrial palmitoyl-CoA synthetase activity decreased gradually. The correlations may be interpreted as reflecting a common regulation mechanism for palmitoyl-CoA hydrolase and peroxisomal beta-oxidation enzymes, i.e., the cellular level of long-chain acyl-CoA acting as the metabolic message for peroxisomal proliferation resulting in induction of peroxisomal beta-oxidation and palmitoyl-CoA hydrolase activity. The findings are discussed with regard to their possible consequences for mitochondrial fatty acid oxidation and the conversion of long-chain acyl-L-carnitine to acyl-CoA derivatives.

Abstract
Palmitoyl-CoA hydrolase [EC 3.1.2.2.] activity in rat liver was found to be enhanced by high fat diets. Partially hydrogenated marine oil and high-erucic acid rapeseed oil diets produced a greater increase than a diet containing soybean oil. With diets containing from 5 to 30% (w/w) of partially hydrogenated marine oil the increase in palmitoyl-CoA hydrolase activity was similar to the increase observed in peroxisomal beta-oxidation activity (correlation coefficient r = 0.94). A positive correlation (r = 0.86) also was observed between the activity of palmitoyl-CoA hydrolase and previously determined levels of long-chain acyl-CoA. The results presented may suggest a common "induction" mechanism for palmitoyl-CoA hydrolase and peroxisomal beta-oxidation enzymes, possibly exerted through an increased cellular level of long-chain acyl-CoA.

Abstract
The present study has confirmed previous findings of long-chain acyl-CoA hydrolase activities in the mitochondrial and microsomal fractions of the normal rat liver. In addition, experimental evidence is presented in support of a peroxisomal localization of long-chain acyl-CoA hydrolase activity. (a) Analytical differential centrifugation of homogenates from normal rat liver revealed that this activity (using palmitoyl-CoA as the substrate) was also present in a population of particles with an average sedimentation coefficient of 6740 S, characteristic of peroxisomal marker enzymes. (b) The subcellular distribution of the hydrolase activity was greatly affected by administration of the peroxisomal proliferators clofibrate and tiadenol. The specific activity was enhanced in the mitochondrial fraction and in a population of particles with an average sedimentation coefficient of 4400 S, characteristic of peroxisomal marker enzymes. Three populations of particles containing lysosomal marker enzymes were found by analytical differential centrifugation, both in normal and clofibrate-treated rats. Our data do not support the proposal that palmitoyl-CoA hydrolase and acid phosphatase belong to the same subcellular particles. In livers from rats treated with peroxisomal proliferators, the specific activity of palmitoyl-CoA hydrolase was also enhanced in the particle-free supernatant. Evidence is presented that this activity at least in part, is related to the peroxisomal proliferation.

Abstract
In the livers of fasted rats, the activity of mitochondrial palmitoyl-CoA hydrolase was increased whereas the microsomal palmitoyl-CoA hydrolase activity decreased. Refeeding with a high-carbohydrate diet (glucose), the corresponding enzyme activities were decreased while refeeding with a high-fat diet (sheep tallow) increased the enzyme activities over the control values. The increased content of long-chain acyl-CoA and free CoASH under fasting and fat-refeeding was mainly attributed to the mitochondrial fraction with the remainder in the light mitochondrial fraction which contains peroxisomes. The results suggest a correlation of the compartmentation of the palmitoyl-CoA hydrolase and the content and compartmentation of the CoA derivatives in the liver under different nutritional states. The peroxisomal palmitoyl-CoA oxidase activity was increased by fasting. Fat-refeeding increased the activity even more; 1.8-fold as compared to the fasting animals. On the other hand, the activities of other peroxisomal enzymes which are not directly involved in the fatty acid metabolism such as urate oxidase were decreased to approximately the same extent by fasting. Re-feeding with glucose and fat further decreased the corresponding enzyme activity, particularly seen in the glucose-refed group.

Abstract
1. The activities of acyl-CoA hydrolase, catalase, urate oxidase and peroxisomal palmitoyl-CoA oxidation as well as the protein content and the level of CoASH and long-chain acyl-CoA were measured in subcellular fractions of liver from rats fed diets containing phenobarbital (0.1% w/w) or clofibrate (0.3% w/w). 2. Whereas phenobarbital administration resulted in increased microsomal protein, the clofibrate-induced increase was almost entirely attributed to the mitochondrial fraction with minor contribution from the light mitochondrial fraction. 3. The specific activity of palmitoyl-CoA hydrolase in the microsomal fraction was only slightly affected while the mitochondrial enzyme was increased to a marked extent (3-4-fold) by clofibrate. 4. Phenobarbital administration mainly enhanced the microsomal palmitoyl-CoA hydrolase. 5. The increased long-chain acyl-CoA and CoASH level observed after clofibrate treatment was mainly associated with the mitochondrial, light mitochondrial and cytosolic fractions, while the slight increase in the levels of these compounds found after phenobarbital feeding was largely of microsomal origin. 6. The findings suggest that there is an intraperoxisomal CoASH and long-chain acyl-CoA pool. 7. The specific activity of palmitoyl-CoA hydrolase, catalase and peroxisomal palmitoyl-CoA oxidation was increased in the lipid-rich floating layer of the cytosol-fraction. 8. The changes distribution of the peroxisomal marker enzymes and microsomal palmitoyl-CoA hydrolase after treatment with hypolipidemic drugs may be related to the origin of peroxisomes.
