Studies on a green pigment in the erythrocytes of skipjack. III. Sugar, base, phosphate, and lipid moieties.

Abstract

The three major components (I, II, and VI) of the green pigment from skipjack erythrocytes were analyzed for sugar, base, phosphate, and lipid moieties. The sugar moiety was mainly ribose, and its content ranged from 12 to 17% depending upon the component. The base moiety was composed of adenine, guanine, cytosine, and uracil, the total content being 3-4% in all three components. The phosphate content ranged from 6% (component VI) to 18%. (component II). The lipid content of component II, the only component analyzed for lipid, was 15% and consisted of glyceride, free fatty acid, and phospholipid.
