Polar lipids of marine macrophytic algae as chemotaxonomic markers

Description
Summary:The polar lipid composition of 49 species of marine macrophytic algae was investigated. Each division of seaweeds and each class of Phaeophyta and Chlorophyta have distinctive peculiarities in the composition of their phospholipids and other polar lipids. Rhodophyta are the richest in phosphatidylcholine and contain unsaponifiable phospholipid. Brown algae of the class Phaeosporophyceae differ from those of the class Cyclosporophyceae by the presence of phosphatidylcholine and the absence of two unusual polar lipids. Only the Chlorophyta contain phosphatidylserine and diacylglyceryltrimethylhomoserine. The Chlorophyceae differ from the Siphonophyceae by the absence of phosphatidylcholine. Correlation between polar lipid composition and botanical taxonomy of marine algae is discussed.
