Glycosaminoglycans from the rooster comb and wattle.

Glycosaminoglycans (GAG) were isolated from the rooster comb and wattle by digestion with papain and analyzed by cellulose acetate electrophoresis and enzymatic digestion. The results indicated that the concentration of GAG uronic acid is approximately two-fold greater (P less than .01) in the comb than in the wattle. In both tissues, hyaluronic acid was the major GAG, with a small proportion of dermatan sulfate.
