(glycosyldiacylglycerol) Any of a group of * acylglycerols containing a carbohydrate group, commonly a mono-, di-, or trisaccharide or an amino sugar. Glycolipids are the major lipid constituents of chloroplasts. No triacylglycerols are found in chloroplasts and phosphoglycerides are present only in small quantities. The commonest glycolipids are monogalactosyl- and digalactosyldiacylglycerols. They are synthesized from diacylglycerols and UDP derivatives of galactose.
