摘    要:共轭亚油酸(CLA)是一组位置和构象异构体的总称,异构体c9t11-CLA 和t10c12-CLA 或二者的协同作用赋予了CLA 的许多生理功能,比如抗癌、降低体脂含量、预防糖尿病的发生、降低血脂抑制动脉粥样硬化等;异构体c9t11-CLA 和t10c12-CLA 在结构及来源上存在一定差别--由于双键位置的不同,t10c12-CLA 异构体比c9t11-CLA 异构体更容易氧化;而在生理功能上二者也有差异-- c9t11-CLA 异构体的主要作用是抗癌,而 t10c12-CLA 则是降低体脂、血脂等,大量单一异构体的体外实验研究表明二者在抗癌及脂肪代谢的调节上作用机制也不尽相同。

关 键 词:c9t11-  共轭亚油酸  t10c12-  共轭亚油酸  抗癌作用  机体构成  脂肪代谢

Abstract:Conjugated linoleic acid (CLA) is a mixture of positional and geometric isomers, and numerous biological functions such as anticancer, reduction of body fat content, diabetes prevention, lower blood lipids and inhibition of arteriosclerosis are due to individual or synergistic action of most isomers including c9t11- and t10c12-CLA. Because of different positions of double bounds between c9t11- and t10c12-CLA isomers, high oxidization possibility of c9t11-CLA isomer was observed. Therefore, c9t11-CLA isomer exhibited a major responsibility for anticarcinogenic effect, whereas, t10c12-CLA isomer exhibited stronger reduction effect on body fat and blood lipids. Increasing studies suggested that the mechanisms of both isomers on cancer and fat metabolism were different.
Keywords:c9t11-CLA  t10c12-CLA  anticancer  body composition  fat metabolism
