Introduction
Enzymes are macromolecule that acts as a catalyst, a chemical agent that speeds up a reaction without being consumed by the reaction. They convert the complex of the enzyme and the substrate to the transition state so that the product can easily be formed at the active site. In this experiment, we are focusing on enzymes that are proteins. Lactose is a disaccharide composed of D-galactose and D-glucose. The thermal agitation of the enzyme molecule disrupts the hydrogen bonds, ionic bonds, and other weak interactions that stabilize the active shape of the enzyme, and the protein molecule eventually denatures. The types are various, and each has a unique highorder structure and exhibits unique properties. Types vary and lose their inherent high dimensional structure, which is altered by physical and chemical changes and called protein denaturation. A familiar example of heat-caused denaturation are the changes observed in the albumin protein of egg whites when they are cooked.
