Conjugated linoleic acid (CLA) has been shown to reduce body fat mass (BFM) in animals. To investigate the dose-response relationships of conjugated linoleic acid with regard to BFM in humans, a randomized, double-blind study including 60 overweight or obese volunteers (body mass index 25-35 kg/m(2)) was performed. The subjects were divided into five groups receiving placebo (9 g olive oil), 1....

25 26 27 28 29 30 This study describes a rapid method for identifying bacteria which convert free linoleic acid to conjugated linoleic acid (CLA). The method is based on the spectrophotometric detection of CLA and compares well to the standard GLC method. This method should facilitate the high throughput screening of bacterial isolates for the ability to produce conjugated fatty acids.

In this paper we describe a rapid method for identifying bacteria which convert free linoleic acid to conjugated linoleic acid (CLA). This method is based on spectrophotometric detection of CLA and compares well with the standard gas-liquid chromatography method. This method should facilitate high-throughput screening of bacterial isolates for the ability to produce conjugated fatty acids.

Despite its benefits, conjugated linoleic acid (CLA) may cause side effects after long-term administration. Because of this and the controversial efficacy of CLA in humans, alternative biomolecules that may be used as functional ingredients have been studied in recent years. Thus, conjugated linolenic acid (CLNA) has been reported to be a potential anti-obesity molecule which may have additiona...

Activity-directed isolation of the ethyl acetate, methylene chloride and n-hexane fractions of Gloiopeltis furcata resulted in the isolation of 18 compounds. Their structures were elucidated as 2-(3-hydroxy-5-oxotetrahydrofuran-3-yl)acetic acid (1), glutaric acid (2), succinic acid (3), nicotinic acid (4), (E)-4-hydroxyhex-2-enoic acid (5), cholesterol (6), 7-hydroxycholesterol (7), uridine (8)...

1. A major component of the lipids in aqueous (pH7.5) homogenates of tuber tissue from Solanum tuberosum was isolated and characterized as 9-(nona-1',3'-dienoxy)non-8-enoic acid. 2. This novel unsaturated ether fatty acid derivative, which contains a butadienylvinyl ether function, has the structure: [Formula: see text] and is formed from linoleic acid by a sequence of enzymic reactions. 3. A p...
