Book excerpt: One of the most important industrial proteins is collagen. On treatment with tannins or certain inorganic salts, it is converted into leather. This process is known as tanning. By prolonged heating with water, collagen is changed into glue, which has a large number of commercial applications, such as the making of paper, photographic plates, and adhesives. This Circular gives a general outline of the physical and chemical properties of collagen, and was prepared for the large numbers of chemists employed in industries in which this material or its transition product, glue, is processed.
