[Research Progress of Fatty Acid Desaturase 2 Gene in Glycolipid Metabolism]

The fatty acid desaturase 2 (FADS2) gene encodes delta-6 desaturase (D6D) and is a member of the fatty acid desaturase gene family.D6D is the key enzyme catalyzing the transformation of linoleic acid and α-linolenic acid to long-chain polyunsaturated fatty acid (LC-PUFA).LC-PUFA play a crucial role in regulating the glycolipid metabolism of living organisms.In recent years,the activity of D6D and the single nucleotide polymorphism (SNP) of FADS2 gene have become a hot topic in the research on glycolipid metabolism.This article reviews the role of FADS2 gene in glycolipid metabolism.
