Fourteen species of marine red algae belonging to the Rhodophyta, 13 species of marine green algae belonging to the Chlorophyta and two species of the marine grass from the Embryophyta wire examined for their glycolipid and fatty acid compositions. Characteristic of red algae was their high content of 20:4 and 20:5. The green algal species were unusual in containing 16:4 varying from 4.9 to 23.1% of the total fatty acids; 16:0, 18:1 and 18:3 acids were also found in high amounts. Glycolipid contents of total lipid extracts of red algae ranged from 16.4 to 31.8 micromoles g-1 dry wt, while those in green algae varied from 10.5 to 31.8. The red algae contained almost equal quantities of monoglycosyldiacylglycerol (MGDG), diglycosyldiacylglycerol (DGDG) and sulphaquinovosyldiacyl-glycerol with some exceptions. MGDG and DGDG were the major glycolipids in green algae and marine grasses, respectively.
