title: Chemical composition of glycosaminoglycan fractions from the comb and wattle of single comb white Leghorn roosters.
abstract: Glycosaminoglycan (GAG) fractions were isolated from papain digests of comb and wattle tissues of 52-wk-old Single Comb White Leghorn roosters and the chemical composition of each fraction was examined. Total GAG concentrations were greater in the comb than in the wattle tissue with the ratio of hyaluronic acid to sulfated GAG being similar between the two tissues. L-iduronosyl-N-acetylgalactosamine-4-sulfate was the predominant disaccharide unit in the sulfated GAG fraction.
