| Abstract: | The distribution of monogalactosyldiacylglyceride (MGDG), digalactosyldiacylglyceride (DGDG), and sulfoquinovosyldiacylglyceride (SQDG) in red, brown, and green algae and marine grasses was studied. Domination of SQDG among the glycolipids is typical of brown algae of the order Fucales. Low SQDG content with high MGDG and DGDG is typical of marine grasses. Marine algae and grasses are characterized by common trends in the distribution of fatty acids (FA) among the glycolipids. Polyunsaturated FA of the (n-3) series are concentrated primarily in galactolipids. The highest unsaturation in red and green algae occurs in MGDG; in brown algae and marine grasses, in DGDG. SQDG has a high content of saturated FA. |
