Abstract
Summary
A volumetric study has been conducted of the effects of collagenase solutions on isoelectric and treated bovine hide powder collagen preparations. The data indicate that the enzyme solution used is active against hide powder collagen, that the effects of the collagenase noted here are independent of pH and that pretreatment of hide powder with the autoxidation polymers of homogentisic acid (HGA-OP) results in significant diminution of the effects of collagenase. With earlier data indicating that HGA-OP binds to hide powder, the current data are interpreted as indicating that HGA-OP acts as an effective tanning agent for hide powder collagen.
