  Structure of the “heterocyst glycolipids” of the marine cyanobacterium Nodularia harveyana

  摘要：

  The ''heterocyst glycolipids'' have been reported to take part in the protection of the specialized cyanobacterial cells capable of N2 fixation against the penetration Of O2. For the first time such glycolipids have been isolated in a pure form from a cyanobacterium, Nodularia harveyana, and their structures have been established by spectroscopic and chemical means to be 1-(O-alpha-D-glucopyranosyl)-3R,25R-hexacosanediol, 1-(O-alpha-D-glucopyranosyl)-3S,25R-hexacosanediol and 1-(O-alpha-D-glucopyranosyl)-3-keto-25R-hexacosanol.
