MetaCyc Compound Class: a 1,3-diglyceride

Synonyms: a 1,3-DAG, a 1,3-diacyl-sn-glycerol, a 1,3-diacylglycerol

Superclasses: a lipid a glycerolipid a glyceride a diglyceride

Summary:
The name glyceride describes any ester of glycerol with fatty acids. Depending on the number of fatty acids, glycerides are classified as monoglycerides, diglycerides and triglycerides.

Diglycerides are classified further into 1,2-diglycerides and 1,3-diglycerides.
