Conjugated linoleic acid (CLA) is a group of geometrical and positional isomers of linoleic acid (C18:2, cis-9, cis-12). In contrast to linoleic acid, double bonds in CLA are usually located at positions 9 and 11 or 10 and 12 and each double bond can be either in the cis or trans configuration. Meat and dairy products from ruminant animals (such as milk, butter, yogurt and cheese) are the princ...
Conjugated linoleic acid (CLA) is a prime substrate for intra-gastric nitration giving rise to the formation of nitro-conjugated linoleic acid (NO2-CLA). Herein, NO2-CLA generation is demonstrated within the context of acute inflammatory responses both in vitro and in vivo. Macrophage activation resulted in dose- and time-dependent CLA nitration and also in the production of secondary electroph...
BACKGROUND Trans fatty acids are produced either by industrial hydrogenation or by biohydrogenation in the rumens of cows and sheep. Industrial trans fatty acids lower HDL cholesterol, raise LDL cholesterol, and increase the risk of coronary heart disease. The effects of conjugated linoleic acid and trans fatty acids from ruminant animals are less clear. We reviewed the literature, estimated th...
Conjugated linoleic acid (CLA) is a collective term used for fatty acids with a conjugated double bond that are geometrical and positional isomers of linoleic acid. Anti-obesity and anti-cancer properties, an immunopotentiation effect, and promotion of bone formation by CLA have been shown in cell culture and animal studies. A mixture of 9c11t- and 10t12c-CLA is now used as a health food supple...
This is the protocol of a study aiming to assess the impact of conjugated linoleic acid (CLA) on body mass and composition, carbohydrate and fat digestion and absorption, total energy expenditure, lipid profi le, polyunsaturated fatty acids levels, markers of endothelial dysfunction and mineral status in humans. Seventyfour adult volunteers (BMI ≥ 25 kg/m) will be randomized to receive 3.0 g of...
Conjugated linoleic acid (CLA) is a collective term for a mixture of positional and geometric isomers of conjugated dienoic derivatives of linoleic acid. CLA has received considerable attention as a result of animal experiments that report anti-carcinogenic, anti-atherogenic and anti-diabetic properties, and modulation of body composition and immune function. Several studies of CLA supplementat...
Effect of Feeding Canola or Sunflower Seeds on Conjugated Linoleic Acid Enrichment in Cow’s Milk Fat
Two experiments studied the effects of canola or sunflower seed supplementation on conjugated linoleic acid (CLA) concentration in milk fat of lactating cows. In each experiment, only eight cows in early lactation were available to assign to one of two treatments in a completely randomized design and were fed individually for 12 wk. Experiment 1 compared similar diets with or without the additi...
Spermatogenesis is a physiological reaction dependent to harmony of gonadotropins and steroid hormones activities. Conjugated linoleic acid is a group of long chain unsaturated fatty acids of a conjugated bound which are found in dairy products, beef and lamb. There are strong reasons that g/kg of food affects mediators involved in spermatogenesis. The aim of this study was determination of eff...
The dietary dose responsiveness of conjugated linoleic acid (CLA) addition relative to the fatty acid profile of edible lean tissue was examined in grower pigs treated with or without porcine somatotropin (pST). Gilts and barrows were fed CLA at 0, 0.25, 0.5, 1.0, or 2.0% of diet by weight from 20 to 55 kg BW. Additional pigs were administered (pST) at 0 or 100 microg x kg BW x d(-1) and fed ei...
Atherosclerosis is an inflammatory disease characterised by the accumulation of lipids and their metabolites in the artery wall. During inflammation circulating LDL are taken up by macrophages through two major scavenger receptors: CD36 and scavenger receptor A (SRA). Fatty acids that are common in food, e.g. linoleic acid and n-3 unsaturated fatty acids can modulate expression of CD36 on the m...
