Acetyl CoA Carboxylase and Regulation
Strict control of fatty acid biosynthesis at key step
Local, hormone, and gene regulation
Involved in regulation of beta oxidation
When fuel is high, acetyl CoA is plentiful, and malonyl CoA is produced
Malonyl CoA may decrease appetite
Malonyl CoA inhibits acylcarnitine transferase
No Fatty acids can get into mitochondria for oxidation
