  • Title: Characterization and synthesis of mono- and diphytanyl ethers of glycerol.
    Author: Joo CN, Shier T, Kates M.
    Journal: J Lipid Res; 1968 Nov; 9(6):782-8. PubMed ID: 5685270.
    Abstract:
    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,11'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 alpha- and -isomers. The alpha-isomer was found to be identical with the synthetic 3-O-(3'R,7'R,11'R,15'-tetramethylhexadecyl)-sn-glycerol, and the -isomer was identical with the synthetic 2-O-(3'R,7'R,11'R,15'-tetramethylhexadecyl) glycerol.
