Fatty Acid Synthesis (De Novo Lipogenesis) Lipid Metabolism · Cytosol

step 6 Irreversible/directional

Acetyl-CoA + ACP → acetyl-ACP + CoA-SH

Converts Acetyl-CoA ACP (acyl carrier protein) into Acetyl-ACP CoA-SH

Notes

The acetyl group is transferred by the acetyl/malonyl transferase activity of the multifunctional fatty acid synthase complex to its acyl-carrier protein (ACP) phosphopantetheine thiol; the acetyl group is then transferred to the active-site cysteine of the β-ketoacyl synthase (KS) domain. ACP contains 4′-phosphopantetheine, derived from pantothenate.

step 7 Irreversible/directional

Malonyl-CoA + ACP → malonyl-ACP + CoA-SH

Converts Malonyl-CoA ACP (acyl carrier protein) into Malonyl-ACP CoA-SH

Notes

The FAS malonyl/acetyl transferase loads malonyl-CoA onto ACP. One acetyl primer and seven malonyl units are required to make palmitate.
