On the Control of Fatty Acid Compositions of Plant Glycerolipids

  • Grattan Roughan


Just a few years ago, a rational explanation of the sometimes confusing fatty acyl compositions of plant glycerolipids seemd a long way off. The perversity of these lipids was legendary1; different phospholipids within the same plant had their acyl groups arranged differently; both the digalactosyl diacylglycerol (DGD) and the sulfolipid (SL) had different dispositions of fatty acids depending upon their source; the hexadeca-trans-3-enoate (t16: 1), which is unique to plant phosphatidylglycerol (PG), was strictly confined to the sn-2 position; the monogalactosyl diacylglycerol (MGD) of some plants contained up to 40% of its constituent fatty acids as hexadecatrienoate (16: 3) which however, was completely missing from the MGD of other plants. Even so, there were sufficient clues to suggest that the problem of fatty acid distribution within plant glycerolipids might be soluble.
