step 8 Irreversible/directional

Acetyl-KS + malonyl-ACP → acetoacetyl-ACP + CO2

Converts Acetyl-KS Malonyl-ACP into Acetoacetyl-ACP CO2

Notes

The β-ketoacyl-ACP synthase (KS) domain catalyzes decarboxylative condensation, producing a four-carbon β-ketoacyl-ACP. No ATP is consumed in this condensation; decarboxylation of malonyl-ACP provides the thermodynamic drive. In subsequent rounds, the growing acyl chain replaces acetyl-KS.
