It is a unique phospholipid with in essence a dimeric structure, having four acyl groups and potentially carrying two negative charges. It occurs almost exclusively in mitochondria in ... WebIn Gram-positive bacteria, which have a single phospholipid bilayer coated with peptidoglycans, phosphatidylglycerol can be as high as 60% of the phospholipids (together with glycosyldiacylglycerols). In many bacteria, the diacyl form of the lipid predominates, but in others the alkylacyl and alkenylacyl forms are more abundant.
