  • 功能：
    Stearoyl-CoA desaturase that utilizes O(2) and electrons from reduced cytochrome b5 to introduce the first double bond into saturated fatty acyl-CoA substrates. Catalyzes the insertion of a cis double bond at the delta-9 position into fatty acyl-CoA substrates including palmitoyl-CoA and stearoyl-CoA. Gives rise to a mixture of 16:1 and 18:1 unsaturated fatty acids. Plays an important role in lipid biosynthesis. Plays an important role in regulating the expression of genes that are involved in lipogenesis and in regulating mitochondrial fatty acid oxidation. Plays an important role in body energy homeostasis. Contributes to the biosynthesis of membrane phospholipids, cholesterol esters and triglycerides.

    1. Expression of SCD1 was downregulated through reduced transcription and abundance of the transcription factor sterol regulatory element-binding protein 1 (SREBP1c).This effect was augmented by local chromatin tightening and DNA methylation at and around the SREBP1c binding site in the SCD1 promoter PMID: 29274956

    10. This study presents evidence that there are breed- and diet-induced variations on lipid metabolism in the muscle, which may be, at least partially, modulated by the stearoyl-CoA desaturase (SCD) gene expression levels. PMID: 23467818

    28. study concludes that the higher desaturase activity of SCD allele C in the composition of milk fat can only be appreciated on myristic and caproleic FA because of the different pathways from which milk FA derive PMID: 17582140
