Isolation and identification of acetyl-CoA carboxylase from rainbow trout (Salmo gairdneri) liver
Lipids - Tập 24 - Trang 187-192 - 1989
Acetyl-CoA carboxylase is the pivotal enzyme in the de novo synthesis of fatty acids and is the only carboxylase with a biotin-containing subunit greater than 200,000 daltons. The biotin moiety is covalently linked to the active site and has a high affinity (Kd=10−15 M) for the protein avidin. This relationship has been used in previous studies to identify acetyl-CoA carboxylase isolated from mamm......
The effect of dietary erucic acid on cardiac triglycerides and free fatty acid levels in ratsAbstract Male Sprague‐Dawley rats, 3 weeks of age, were fed semisynthetic diets containing test oils at 20% by weight for 3 days, 1 week, and 16 weeks. The test oils contained up to 22.3% erucic acid. Growth retardation was evident in rats fed rapeseed oil high in erucic acid, and soybean oil and Tower rapeseed oil diets containing about 5% erucic acid. Cardiac trig... ...

Daily variations of the biosynthesis and composition of fatty acids in rats fed on complete and fat-free diets
Lipids - Tập 19 - Trang 91-95 - 1984
This report describes the daily changes in fatty acid composition and fatty acid desaturation in rats feeding on a complete diet and a fat-free diet successively. Rats on a complete diet showed a good homeostasis in the percentage of fatty acid in plasma, with a possible palmitic acid rhythm, but the fat-free diet initiated an essential fatty acid-deficient pattern in a few hours. The light-dark p......
Influence of diet on the kinetic behavior of hepatic carnitine palmitoyltransferase I toward different acyl CoA esters
Lipids - Tập 32 - Trang 31-37 - 1997
The influence of diet on the kinetics of the overt form of rat liver mitochondrial carnitine palmitoyltransferase (CPT I; EC 2.3.1.21) was studied using rats fed either a low-fat diet (3% w/w fat), or diets which were supplemented with either olive oil (OO), safflower oil (SO) or menhaden (fish) oil (MO) to 20% w/w of fat (high fat diets). When animals were fed each of these four diets for 10 days......
Interaction Between VLDL and Phosphatidylcholine Liposomes Generates New γ-LpE-like Particles
Lipids - Tập 49 - Trang 143-153 - 2013
One of the subfractions of HDL involved in reverse cholesterol transport is γ-LpE. It has been assumed that, like preβ-LpAI, it can be generated during the interaction between phosphatidylcholine liposomes and lipoproteins and can contribute to more efficient cholesterol efflux after the introduction of liposomes to plasma. However, there has been no evidence concerning what the sources of these p......
Effect of the nature and amount of dietary energy on lipid composition of rat bone marrow
Lipids - Tập 10 - Trang 584-590 - 1975
The effect of the nature and amount of dietary calories on the lipid composition of bone marrow of rats was studied. Male weanling rats were fed 3 isocaloric diets, containing high carbohydrate, normal protein, and high protein, and a fourth high fat diet for 49 days. Feeding of the high carbohydrate, high protein, and high fat diets caused a significant increase in the level of total lipids compa......
Clofibrate and Nafenopin (SU-13437): Effects on plasma clearance and tissue distribution of chylomicron triglyceride in the dog
Lipids - Tập 7 - Trang 644-652 - 1972
Adult male dogs, which received orally for 21 days either no drug, 75 mg/kg/day of clofibrate or 25 mg/kg/day of nafenopin, were injected iv with14C-labeled chylomicron-lipid, essentially chylomicron-triglyceride fatty acid, at 0.2 g of fat per kilogram body weight. At times from 2–160 min after injection, samples of blood, liver, skeletal muscle and adipose tissue were removed, weighed and assaye......
Low serum docosahexaenoic acid is a significant risk factor for alzheimer’s dementia

Comparative investigation of human stratum corneum ceramides
Lipids - Tập 36 - Trang 299-304 - 2001
The stratum corneum (SC) requires ceramides, cholesterol, and fatty acids to provide the cutaneous permeability barrier. SC lipids can be analyzed by normal-phase high-performance thin-layer chromatography (HPTLC). However, without further analysis, some uncertainty remains about the molecular composition of lipids represented by every TLC band of an unknown sample. We therefore analyzed each cera......
The development of coronary thrombosis following myocardial infarctionAbstract One hundred twenty‐one patients who died from myocardial infarction were studied. Occlusive coronary artery thrombosis was present in 32%. In 68% of these, the infarct developed first. Factors inducing thrombus formation include fall in systemic blood pressure, alteration of blood flow, shock, and size of infarct. Factors inducing infarction, apart from hyp... ...
