Application
亚油酸，共轭甲酯（CLA）已用作通过高效液相色谱（HPLC）、气相色谱-质谱法测定牛奶样品中 CLA 异构体的标准品。它也已用于生产 sn-1,3-二酰基甘油。
Biochem/physiol Actions
共轭亚油酸（CLA）异构体作为补品可抑制许多人类癌细胞系的生长。它还具有免疫刺激特性，可预防糖尿病并减少动脉粥样硬化。
General description
共轭亚油酸（CLA）描述了具有共轭双键的 C18:2 脂肪酸（FA）的位置和几何异构体。根据体外实验和动物研究，顺式-9，反式-11 CLA 被认为是 牛奶中 CLA 的主要异构体。人类饮食中 CLA 的主要来源是反刍动物脂肪。
Other Notes
顺式和反式-9,11-和-10,12-十八碳二烯酸甲酯的混合物。异构体比例可能因批次而异。
