title: A novel glycolipid, 1,2-diacyl-3-alpha-D-glucuronopyranosyl-sn-glycerol taurineamide, from the budding seawater bacterium Hyphomonas jannaschiana.
abstract: A previously unknown glycolipid has been isolated from the budding seawater bacterium Hyphomonas jannaschiana VP-2T devoid of phospholipids. Using a combination of chromatographic, spectrometric, enzymic- and chemical-degradation methods, the structure of the lipid has been determined to be 1,2-diacyl-3-alpha-D-glucuronopyranosyl-sn-glycerol taurineamide. Its main fatty acyls are n-16:0, cis-16:1 omega 7, n-18:0, cis-18:1 omega 7, and n-19:0. The hydroxyl at the sn-1 position of the glycerol residue is acylated predominantly with unsaturated fatty acids, and the secondary hydroxyl at the sn-2 carbon is acylated mainly with saturated ones.
