DETAILS

Description (English)
Biochem/physiol Actions
Palmitic acid is a straight-chain 16-carbon fatty acid. Diets rich in palmitic acid, along with lauric and myristic acids, are associated with increased serum levels of low-density lipoprotein cholesterol. Palmitic acid is the first fatty acid produced by lipogenesis. It is a negative regulator of acetyl-CoA carboxylase (ACC) and is implicated in fatty acid-induced insulin resistance.
