DescriptionCL(19:1(9Z)/16:1(9Z)/19:1(9Z)/16:1(9Z)) is a cardiolipin (CL). Cardiolipins are sometimes called a 'double' phospholipid because they have four fatty acid tails, instead of the usual two. CL(19:1(9Z)/16:1(9Z)/19:1(9Z)/16:1(9Z)) contains two chains of (9Z-nonadecenoyl) at the C1 and C3 positions, two chains of (9Z-hexadecenoyl) at the C2 and C4 positions. While the theoretical charge of cardiolipins is -2, under normal physiological conditions (pH near 7), the molecule may carry only one negative charge. In prokaryotes such as E. coli, the enzyme known as diphosphatidylglycerol synthase catalyses the transfer of the phosphatidyl moiety of one phosphatidylglycerol to the free 3'-hydroxyl group of another, with the elimination of one molecule of glycerol. In E. coli, which acylates its glycerophospholipids with acyl chains ranging in length from 12 to 19 carbons and possibly containing an unsaturation, or a cyclopropane group more than 100 possible CL molecular species are theoretically possible. E. coli membranes consist of ~5% cardiolipin (CL), 20-25% phosphatidylglycerol (PG), and 70-80% phosphatidylethanolamine (PE) as well as smaller amounts of phosphatidylserine (PS). CL is distributed between the two leaflets of the bilayers and is located preferentially at the poles and septa in E. coli and other rod-shaped bacteria. It is known that the polar positioning of the proline transporter ProP and the mechanosensitive ion channel MscS in E. coli is dependent on CL. It is believed that cell shape may influence the localization of CL and the localization of certain membrane proteins.

Chemical Taxonomy
Description belongs to the class of organic compounds known as cardiolipins. These are glycerophospholipids in which the O1 and O3 oxygen atoms of the central glycerol moiety are each linked to one 1,2-diacylglycerol chain. Their general formula is OC(COP(O)(=O)OC[C@@H](CO[R1])O[R2])COP(O)(=O)OC[C@@H](CO[R3])O[R4], where R1-R4 are four fatty acyl chains.
