Lipids, Fatty Acids and Sterols of Cystoseira abies - marina (original) (raw)

Lipid content, fatty acids and sterol composition of Cystoseira abies-marina and total fatty acids of C. humilis from Gran Canaria were studied. A high content of polyunsaturated fatty acids 16 : 3 and 16: 4 was found. Their content in rnonogalactosyldiacylglycerols is over 90%. Triacylglycerols and phospholípids contain rnainly arachidonic and eicosapentaenoic acids. Reasons for the differences in the composition of fatty acids and sterols of various species of Cystoseira are discussed. Sorne technological approaches are recommended.
