About the structure and biological function of MAG
Structure. Monoacylglycerols (monoglycerides, MAG, or MG) belong to the glycerol esters lipid group within the glycerolipids category. Their structure consists of a glycerol backbone linked to one fatty acid. The fatty acid can be of variable length, hydroxylated, and contain double bonds.
Function. Monoacylglycerols serve many biological functions. MAGs are important intermediates in the biosynthesis of glycerol lipids and phospholipids. In animals, they support the absorption of lipid soluble vitamins and are also known to be involved in the regulation of skin barrier function to maintain transepidermal water loss. Further, monoacylglycerols function as signaling molecules and have been shown to possess anti-inflammatory properties.
