How Enzymes Act As Protein Catalysts in Biochemical Processes
Catalysis refers to the speeding up of a chemical reaction by a catalyst. A catalyst is a substance that accelerates a chemical reaction but does not undergo a permanent chemical change in the process. Enzymes are catalysts whose building blocks are amino acids: they are proteins. Enzymes also exhibit a defined three-dimensional structure. In addition, they have a cleft on their surface called active site. The active site is the region where substrate interactions take place. Enzymes play important roles in fructose metabolism. The first step of fructose metabolism in the liver is the phosphorylation of ...
