脂肪酸合酶
脂肪酸合酶（英语：Fatty acid synthase）是一个具有多种功能的酶系统，在哺乳动物中，其分子量高达272kDa。在脂肪酸合酶中，底物和中间产物分子在各个功能结构域（可以位于同一酶分子，也可以位于不同酶分子）中传递直到完成脂肪酸的整个合成过程。

Fatty acid synthase (FAS) is an enzyme that in humans is encoded by the FASN gene.
Fatty acid synthase is a multi-enzyme protein that catalyzes fatty acid synthesis. It is not a single enzyme but a whole enzymatic system composed of two identical 272 kDa multifunctional polypeptides, in which substrates are handed from one functional domain to the next.
