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-α-D-glucopyranosyl)-3R,25R-hexacosanediol, 1-(O-α-D-glucopyranosyl)-3S,25R-hexacosanediol and 1-(O-α-D-glucopyranosyl)-3-keto-25R-hexacosanol.
