The determination of the nitrogenous substances and ammonium salts in leather is used to calculate the skin substance. 1% nitrogen is 5.62% anhydrous skin substance (collagen). In contrast to this, the amide nitrogen content represents a measure of the degradation processes of proteins that have already taken place. Even a slight degradation reduces the amide nitrogen content.
