Cytosolic fatty acid synthase (FAS) complex catalyzes the reaction of acetyl-CoA with 7 malonyl-CoA and 14 NADHP + 14 H+ to form a molecule of palmitate and 7 CO2, 14 NADP+, 8 CoASH, and 6 H2O. The process proceeds via the successive condensations of malonyl groups onto the growing acyl chain,each followed by loss of CO2 and three steps of reduction (Smith et al. 2003).
