Metabolite Identification
Common Name7a,12a-Dihydroxy-5b-cholestan-3-one
DescriptionDG(20:1(11Z)/18:3(6Z,9Z,12Z)/0:0) belongs to the family of Diacylglycerols. These are glycerolipids lipids containing a common glycerol backbone to which at least one fatty acyl group is esterified. DG(20:1(11Z)/18:3(6Z,9Z,12Z)/0:0) is also a substrate of diacylglycerol kinase. It is involved in the phospholipid metabolic pathway.
