摘要:The methanolyzed lipids of the extreme halophile, Halobacterium cutirubrum , were separated into glycerol diether and glycerol monoether fractions. The diether was shown by synthesis to be 2,3-di- O -(3′ R ,7′ R ,ll′ R ,15′-tetramethylhexadecyl)- sn -glycerol. The monoether fraction was separated by thin-layer chromatography on boric acid-impregnated silicic acid into about equal amounts of α- and β- isomers. The α-isomer was found to be identical with the synthetic 3- O -(3′ R ,7′ R ,ll′ R ,15′-tetramethylhexadecyl)- sn -glycerol, and the β-isomer was identical with the synthetic 2- O -(3′ R ,7′ R ,11′ R ,15′-tetramethylhexadecy1) glycerol.
