Fatty Acid Synthase

Fatty Acid Synthase; also FAS or FASN) is a cytosolic member of the short chain dehydrogenase/reductase family 27X. It is found as an antiparallel homodimer in neurons, skeletal muscle, adipocytes and hepatocytes. FASN catalyzes the formation of palmitic acid from acetylCoA or malonylCoA, and also likely mediates the transfer of fatty acids to peptides.
