| Résumé : |
Variability in the lipid content from one area of a hide to another has prevented accurate comparisons of the chemical compositions of hides. Since the various lipid constituents are the result of different biological processes and serve different purposes within the hide, the contents of certain lipids vary more than others within the hide. In these studies the lipid components were determined in each of five stratigraphic layers taken from 11 areas which represented about two-thirds of the area of the right side of a steerhide. There was considerable variability in the content for each lipid class, both areawise and stratigraphically.
The lipids on the coarse-clipped and fine-clipped hair were determined for nine areas, and these also showed considerable variability. |
