Medchemexpress LLC Acetoacetyl-CoA sodium hydrate | 1420-36-6 | 1 MG
Acetoacetyl-CoA sodium hydrate is a crucial precursor of HMG-CoA in the mevalonate pathway and is essential for cholesterol biosynthesis. It is formed through the catalysis of two acetyl-CoA molecules by acetoacetyl-CoA thiolase, acting as an intermediate in the biological breakdown and synthesis of fatty acids.
- Precursor of HMG-CoA in the mevalonate pathway.
- Essential for cholesterol biosynthesis.
- Intermediate in the biological breakdown and synthesis of fatty acids.
- Formed by the enzyme acetoacetyl-CoA thiolase.
