Study Notes
Fatty Acid Synthesis
- Acetyl-CoA and Malonyl-CoA combine with a cysteine -SH group and adjacent -SH group to form a complex.
- This complex is catalyzed by the fatty acid synthase complex, which is composed of seven enzyme components.
- The reaction ultimately forms palmitate.
Palmitate Synthesis Equation
- The overall equation for the synthesis of palmitate from acetyl-CoA and malonyl-CoA is:
Functional Division
- Lipid metabolism can be functionally divided into different stages or processes.
Phosphopantetheine
- 4'-Phosphopantetheine plays a role in lipid metabolism.
Coenzyme A Components
- Coenzyme A is composed of three key components: pantothenate (K), thiol (Th), and cysteine (Cys).
