Characterization of oligosaccharide units of p-N-collagen type III from dermatosparactic bovine skin.

p-N-collagen type III was extracted from dermatosparactic and normal fetal bovine skin and purified by ion-exchange chromatography using DEAE- and CM-cellulose. Asparagine-linked sugar chains were fractionated by high voltage paper chromatography from the products obtained after hydrazinolysis and reduction with NaB3H4. These oligosaccharides composed of neutral and acidic components are mannose-containing oligosugars of the complex type. Their abundance is much higher in dermatosparactic p-N-collagen type III.
