DescriptionDG(18:0/18:0/0:0) 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(18:0/18:0/0:0) is also a substrate of diacylglycerol kinase. It is involved in the phospholipid metabolic pathway.
