The Basic of Trans-Fatty Acids in Foods: An Update to Prevent Diseases

Abstract

Most of naturally occurring Fatty Acids (FAs) in humans are found in cis (Z)configu-ration. The change of cis-FAs (e.g. monounsaturated and polyunsaturated FAs) in trans (E)-Fas is made by isomerization, which could be geometric and/or positional according to a given car-bon chain.
