ABSTRACT
Branched-chain fatty acids (BCFAs) are a group of fatty acids with methyl branching at variable positions on their fatty acyl chains. BCFAs are not normally encountered in the internal tissues of mammals and are detectable only to a variable extent in the skin surface lipid of animals [1]. For this reason, the physiological signicance of BCFAs in diets has been poorly understood, especially in terms of biological activities of these fatty acids.
