Abstract
The heterocyst glycolipids of the cyanobacterium Cyanospira rippkae ha ve been isolated and their structures established to be 1-()-alpha-D-g lucopyranosyl)-3R,27R-octacosanediol and -(O-alpha-D-glucopyranosyl)-2 7-keto-3R-octacosanol by spectroscopic and chemical means. The absolut e configuration at the two stereogenic centres in the aglycone moiety of the former compound has been established in a single step by Mosher 's method on the triol derivative. The akinetes of C. rippkae contain the same glycolipids.
