We studied the effects of five high-fat semi-purified diets varying at a 4% (w/w) level in either stearic, oleic, linoleic, alpha-linolenic, or gamma-linolenic acid on body fat and energy metabolism in BALB/c mice. A diet containing caprylic, capric, lauric, and myristic acid was used as a reference diet and a diet with 4% conjugated linoleic acid (CLA) was used as a positive control as it is k...
Interest in fortification of human foods, including pork, with conjugated linoleic acid (CLA) is growing and may provide benefits as a neutraceutical based on research evaluating CLA as an anticarcinogen, immune modulator, antiatherogenic agent and a body composition modulator. This study evaluated the combined effects of dietary CLA and supplemental fat source on growth, fatty acid composition...
We evaluated the effects of conjugated linoleic acid (CLA) on growth performance, tissue fatty acid composition and ex vivo lipogenic enzyme activity in piglets (n = 40) reared on sows fed diets supplemented with CLA or linoleic acid (LA). Weaned offspring of both sow groups were offered either a CLA- or LA-enriched starter diet for 35 d. The starter diets were formulated to contain 2 g CLA (co...
The effect of pressure-assisted thermal processing (PATP) in combination with seven synthetic antioxidants was evaluated on the retention of conjugated linoleic acid (CLA) in enriched milk. Milk rich in CLA was first saturated with oxygen, followed by the addition of either catechin, cysteine, ascorbic acid, tannic acid, gallic acid, caffeic acid or p-coumaric acid (500 mg kg-¹ untreated milk)....
Conjugated linoleic acid is a group of positional and geometrical isomers of linoleic acid (C18:2, cis-9, cis-12), an essential fatty acid for human and animals. It is produced in ruminants via biohydrogenation of poly-unsaturated fatty acids and during the mechanical processing of dairy products. Meat and dairy products from ruminant animals (such as milk, butter, yogurt and cheese) are the pr...
چکیده اسید لینولئیک مزدوج (cla) گروهی از ایزومرهای موقعیتی و هندسی اسید لینولئیک است که در آن پیوندهای دوگانه به صورت مزدوج قرار گرفته اند. منابع طبیعی و مهم cla، چربی حاصل از حیوانات نشخوارکننده است (گوشت و محصولات لبنی). روغن های گیاهی نیز حاوی میزان کمی cla (5/0-1/0 میلی گرم به ازای هر گرم چربی) هستند که این مقدار در نتیجه فرایندهای بوگیری و هیدروژناسیون در روغن به وجود می آید. اگرچه اثرات ...
Conjugated linoleic acid (CLA) refers to a group of positional and geometric isomers of linoleic acid. Studies using animal models have shown that CLA reduces adiposity, improves plasma lipoprotein metabolism and insulin sensitivity and reduces arteriosclerosis. Whilst CLA may have therapeutic potential with regard to coronary artery disease risk factors in human subjects, there has been little...
There is no consensus about the effects of conjugated linoleic acid (CLA) on lipid metabolism, especially in animals fed a high-fat diet. Therefore, the objective of the present study was to evaluate the incorporation of CLA isomers into serum, liver and adipose tissue, as well as the oxidative stress generated in rats refed with high-fat diets after a 48 hour fast. Rats were refed with diets c...
Our aim was to assess the effect of two isomers of conjugated linoleic acids (CLA), cis-9,trans-11-CLA (c9,t11-CLA) and trans-10,cis-12-CLA (t10,c12-CLA), on glucose metabolism and hepatic expression of NR4A receptors, key transcription factors regulating gluconeogenesis. ApoE-deficient mice were fed isocaloric, isonitrogenous westernized diets enriched with c9,t11-CLA, t10,c12-CLA or linoleic ...
We analyzed two kinds of dairy fat differing in their contents of cis9, trans11-conjugated linoleic acid (cis9,trans 11-CLA or rumenic acid), and determined the positional distribution of this CLA-isomer within the three sn- positions of the triacylglycerol. In the high rumenic acid fat (HR), the CLA-isomers amounted to 2.1% of total fatty acids, and 0.8% in the low rumenic acid fat (LR). Over ...
