Abstract

The chapter focuses on the occurrence of a special group of glycodiacylglycerolipids, namely the sulfoquinovosyldiacylglycerols (SQDG). The SQDGs differ from each other only in their fatty acid composition. The first representative of the SQDGs was isolated in 1959 from Chlorellapyranoidosa. Additional sources were found in photosynthetic organisms, such as algae, cyanobacteria, sponge, starfish, and surprisingly in the bacteroid forms of Bradyrhizobium Japonicum, because this plant glycolipid is rarely found in bacteria. Structural studies showed that these compounds were l,2-di-0-acyl-3-0-(6-deoxy-6-sulfo-a-D-glucopyranosyl)-L-glycerols. These structures were confirmed by X-ray crystallographic studies of the rubidium salts of the deacylated glycolipids, which were also verified by the 13C-NMR spectra. The fatty acid distribution in natural lipid from various sources has been examined, and as in most phospholipids and glycolipids, a wide spectrum of fatty acids was found. Hexadecanoic acid was found to be present predominantly at the C-2 OH group of the glycerol moiety, and mono-, di-, and trienic derivatives of octadecanoic acid occurred preferentially at the OH-1 of glycerol.
