Structure and enzyme reactions

Abstract
Adsorption of glycogen and starch by coagulated egg albumin, caseinogen, and liver coagulum was studied and compared with the effects of these proteins on the velocity of hydrolysis of the same carbohydrates by pancreatic amylase. Alcohols decreased adsorption and increased reaction velocity in the above systems. Uncoagulated egg white had little effect on the reaction velocity either in presence or absence of alcohols. In the systems containing protein gel, the velocity of the reaction was regulated exclusively by the concentration of unadsorbed substrate.
