DG(20:3n9/0:0/18:2n6)

(2S)-2-Hydroxy-3-[(9Z,12Z)-nonadeca-9,12-dienoyloxy]propyl (5Z,8Z,11Z)-icosa-5,8,11-trienoic acid

C42H72O5 (656.5379462)

DG(20:3n9/0:0/18:2n6) is a diglyceride, or a diacylglycerol (DAG). It is a glyceride consisting of two fatty acid chains covalently bonded to a glycerol molecule through ester linkages. Diacylglycerols can have many different combinations of fatty acids attached at the C-1, C-2, or C-3 positions. DG(20:3n9/0:0/18:2n6), in particular, consists of one chain of mead acid at the C-1 position and one chain of linoleic acid at the C-3 position. The mead acid moiety is derived from fish oils, liver and kidney, while the linoleic acid moiety is derived from seed oils. Mono- and diacylglycerols are common food additives used to blend together certain ingredients, such as oil and water, which would not otherwise blend well. Dacylglycerols are often found in bakery products, beverages, ice cream, chewing gum, shortening, whipped toppings, margarine, and confections.
Synthesis of diacylglycerol begins with glycerol-3-phosphate, which is derived primarily from dihydroxyacetone phosphate, a product of glycolysis (usually in the cytoplasm of liver or adipose tissue cells). Glycerol-3-phosphate is first acylated with acyl-coenzyme A (acyl-CoA) to form lysophosphatidic acid, which is then acylated with another molecule of acyl-CoA to yield phosphatidic acid. Phosphatidic acid is then de-phosphorylated to form diacylglycerol.
Diacylglycerols are precursors to triacylglycerols (triglyceride), which are formed by the addition of a third fatty acid to the diacylglycerol under the catalysis of diglyceride acyltransferase. Since diacylglycerols are synthesized via phosphatidic acid, they will usually contain a saturated fatty acid at the C-1 position on the glycerol moiety and an unsaturated fatty acid at the C-3 position.

(2R)-2-hydroxy-3-[(9Z,12Z)-nonadeca-9,12-dienoyloxy]propyl (8Z,11Z,14Z)-icosa-8,11,14-trienoate

DG(18:2n6/0:0/20:3n6) is a diglyceride, or a diacylglycerol (DAG). It is a glyceride consisting of two fatty acid chains covalently bonded to a glycerol molecule through ester linkages. Diacylglycerols can have many different combinations of fatty acids attached at the C-1, C-2, or C-3 positions. DG(18:2n6/0:0/20:3n6), in particular, consists of one chain of linoleic acid at the C-1 position and one chain of homo-g-linolenic acid at the C-3 position. The linoleic acid moiety is derived from seed oils, while the homo-g-linolenic acid moiety is derived from fish oils, liver and kidney.
