title: Recent advances in conjugated linoleic acid research.
abstract: New results on the physiological properties of conjugated linoleic acid have been published by several working groups, especially showing the effects of single conjugated linoleic acid isomers on carcinogenesis and body composition. Recently, other studies have shown that conjugated linoleic acid has an influence on diabetes mellitus, platelet aggregation and the immune system. Conjugated linoleic acid was found to modify prostaglandin metabolism and delta9-desaturase activity and influence apoptosis. Furthermore, improved analytical methods using 13C nuclear magnetic resonance and silver ion high performance liquid chromatography are available to investigate the composition of conjugated linoleic acid mixtures and the exact structure of separated isomers. Also, the synthesis of isolated isomers is described, as published by different authors, in order to determine further the effects of each single conjugated linoleic acid isomer. In addition, new data on the contents of conjugated linoleic acid in foods, human adipose tissue and fluids are given in this review. More data need to be obtained using isolated isomers, with particular emphasis on studies in humans.
