Biosynthesis of fatty acids

Biotin-dependent enzyme

• acetyl transacylase

• acety coa carboxylase

• malonyl transferase

rate-controlling step

• acetyl transacylase

• acety coa carboxylase

• malonyl transferase

Serves as temporary CO2 carrier before it is transferred to acetyl coa

• ACP

• biotin

• Cysteine

Using the enzyme ATP-citrate lyase, citrate is converted to:

• cytosolic AcoA

• mitochondrial Acoa

reducing agent in fatty acid synthase reactions

• NAD

• NADPH

• FADH2
