Collagen wetting properties

Because of these many complications, it is most encouraging that the data derived from this study were remarkably orderly and that they agreed with predictions based on our studies of simpler model polymers (I, 2, 3). The following can be concluded about the wetting properties of collagen and gelatin ...

Leather can be defined as a material made from the outer skin of any vertebrate (fish, reptile, bird, mammal, etc.) by any process which renders it non-putrescible under warm, moist conditions. A true leather will retain this fundamental property even after repeated wetting and drying. These properties are imparted to the main constituent of the skin, the protein collagen, by introducing additional microbiologically-stable cross-links into the polypeptide structure.
