Fatty acid synthesis in animals is primarily regulated by covalent modification of key enzymes, especially acetyl-CoA carboxylase (ACC), which is the rate-limiting enzyme of the pathway. Covalent modification mainly occurs through reversible phosphorylation and dephosphorylation, allowing the cell to rapidly adjust fatty acid synthesis according to energy status and hormonal signals. ACC catalyzes the conversion of acetyl-CoA to malonyl-CoA, and its activity is directly influenced by its phosphorylation state. When ACC is phosphorylated, it becomes inactive, leading to a decrease in fatty acid synthesis. Conversely, dephosphorylation activates
