Fatty acid synthase (FAS) is a multi-enzyme complex that catalyzes the synthesis of long-chain fatty acids from acetyl-CoA and malonyl-CoA precursors. This complex plays a crucial role in lipid metabolism, which is vital for energy storage, cellular membrane formation, and signaling. The FAS complex consists of several structural components, each contributing to the various steps in fatty acid biosynthesis.

The FAS complex is composed of two main structural units: a dimeric enzyme and a series of catalytic domains. In mammals, FAS is a large, multifunctional enzyme composed of a single polypeptide chain, which dimerizes to form a functional complex. The primary structural components of FAS include:
