Trans-10, cis-12 Conjugated Linoleic Acid
نویسندگان
چکیده
Conjugated linoleic acids (CLA) are a group of linoleic acid isomers having double bonds in conjugated position, i. e. the double bonds are separated by one single bond. Two of the isomers: cis-9, trans-11 (c9, t11) and trans-10, cis-12 (t10, c12) CLA, have been shown to have biologically interesting properties. The c9, t11 CLA has been reported to have anticancer, antidiabetic and anti-inflammatory properties whereas the t10, c12 CLA is known for its antilipogenic ability [1-3].

AIMS To observe the antiobesity activity of trans-10,cis-12-conjugated linoleic acid (CLA)-producing lactobacillus in mice. METHODS AND RESULTS Lactobacillus plantarum PL62, which can grow in the presence of linoleic acid, was selected and studied. The culture supernatant of Lact. plantarum PL62 contained trans-10,cis-12-conjugated linoleic acid (6.4 microg ml(-1)), and the crude enzyme prepa...

The objective of this study was to assess the effect of conjugated linoleic acid isomers (CLAs) on the expression and activity of phospholipases A(2) (PLA(2)) in human macrophages. Macrophages were incubated with 30 microM cis-9, trans-11 and trans-10, cis-12 CLAs for 48 h. After incubation, the total activity of phospholipases as well as the expression of mRNA for cytosolic (cPLA(2)) and secre...

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...

Cultures of ruminal bacteria known to metabolize unsaturated fatty acids were grown in medium containing 50 microg ml(-1) of geometric and positional isomers of conjugated linoleic acid (CLA) or 18 : 1 fatty acids and 37.4 % deuterium oxide to investigate the mechanisms responsible for fatty acid metabolism. Butyrivibrio fibrisolvens JW11 converted cis-9,trans-11-18 : 2 and trans-9,trans-11-18 ...

Abstract Background: Most animal studies have shown that trans-10 and cis-12 isomers of Conjugated linoleic Acid, (CLA) tend to increase insulin resistance. But the effect of equal isomers of CLA (50:50 ratios of cis-9, trans-11: trans-10, cis-12 isomers) on lipid profiles, glucose, and insulin resistance and sensitivity in postmenopausal women is not clear. Methods: In the present study, ...
