| Popis: |
Crystalline preparations of acid-soluble collagen of rat skin in norm and with tryptophan load against a background of the protein-free diet were fractionated by differential salting out using NaCl in concentrations corresponding to precipitation zones of collagen 1,3 and 4. Amino acid composition, electrophoretic mobility in polyacrylamide gel, profiles of elution from CM-cellulose, content of the carbohydrate component and--S--S-bonds were studied in proteins of the mentioned fractions and in the precipitate insoluble after the pepsin action. Essential differences as compared to the normal level in the amino acid composition and elution profiles were detected in the fraction corresponding to collagen I. Quantitative changes in the carbohydrate component and--S--S-bonds occur due to the fraction inaccessible to the persin action. |
