RELATIVE CONFIGURATIONS OF CARBAPSEUDOPENTOSE MOIETIES OF HOPANOIDS OF THE BACTERIUM ZYMOMONAS MOBILIS AND THE CYANOBACTERIUM ANACYSTIS MONTANA

摘要

A bacteriohopanetetrol cyclitol ether with a new configuration of its carbapseudopentose moiety has been isolated from the cyanobacterium 'Anacystis montana' and compared to a similar hopanoid previously isolated from Zymomonas mobilis. As shown by two dimensional H-1-NMR spectroscopy using Nuclear Overhauser Effect correlations, both compounds were diastereomers and differed from a third stereomer found in the biphytanyl lipids of the thermoacidophilic archaebacterium Sulfolobus sp.
