Notes:
Bovine skin corium obtained from freshly slaughtered cattle of increasing biological age showed greater resistance to the action of acids, as measured by extractable collagen. Citrate-soluble content of corium from fetal skin was 30.9%, while that of 3 to 6-wk old calf was 6.4% and of 18-month steer was 3.2%. Similar trends were also noted in neutral salt-soluble (NSC) and pepsin-treated, acid-soluble (PSC) fractions. The greater resistance to degradation in biologically older bovine collagen is thought to be directly related to increased cross-link formation. Gel permeation chromatography, using a newly developed μ-Bondagel column, was found to provide a rapid means for separation and determination of molecular size distribution.
