ACC (Acetyl-CoA Carboxylase)

Acetyl-CoA Carboxylase (ACC) is an enzyme that plays a key role in fat metabolism. It helps convert a molecule called acetyl-CoA into malonyl-CoA, which is a building block for producing fatty acids. Essentially, ACC acts as a switch that determines when the body stores excess nutrients as fat or uses fats for energy. Its activity is regulated by the body's energy needs and hormonal signals, making it vital for maintaining balanced fat synthesis and breakdown.
