This supplement to the excellent treatise on enzymes continues the consideration of proteases. It covers in detail the properties, distribution, purification, preparation, activation, inhibition, optimal conditions of action and mode of action of trypsins, rennins, papains and cathepsins. At the close of the supplements is included an incomplete treatment of phytoproteinases. In connection with the discussion of the rate of secretion of pepsin and trypsin, the author also briefly considers the chemistry of secretin, of gastrin and of the gastric antianemia factor. In completeness and in organization, this supplement continues to live up to the high standards of the previous supplements and the original treatise.
