| Popis: | Intestinal and fecal contents were collected from germfree rats fed a chemically defined diet. The contents, considered to consist mainly of the epithelial mucin of the gastrointestinal tract, were separately extracted with water followed by dialysis and freezedrying. The products obtained had a similar composition, corresponding to substances of glyco-protein nature. The carbohydrate part, constituting about 80 per cent of the material, contained galactose, mannose, fucose, arabinose, xylose, N-acetylglucosamine, N-acetyl-galactosamine and sialic acid. In the peptide moiety serine, threonine, aspartic acid and glutamic acid were the major amino acids. Gel chromatographic experiments indicated, chemical as well as physical heterogeneity of the extracts. |
