Acylglycerols (glycerides) – esters of glycerol and fatty acids. Depending on how many of the three hydroxyl functional groups of glycerol are esterified, monoglycerides monoacylglycerols (monoglycerides), diacylglycerols (diglycerides), or triacylglycerols (triglycerides) can be formed.

Structure, Synthesis, and Occurrence

Diacylglycerol (DAG), termed also as diglyceride is an acylglycerol composed of a glycerol backbone where two of three hydroxy groups are esterified with fatty acid (FA) chains. Depending on which hydroxyl group of glycerol is esterified DAG can exist in three stereochemical forms: sn-1,2-diacylglycerol and sn-2,3-diacylglycerol (termed also α,β-diacylglycerols) as well as sn-1,3-diacylglycerol (termed also α,α’-diacylglycerol) (Fig. 1). In most plant species, DAG is present at low abundance, when compared to triacylglycerols (TAG) (Table 1).
