Welcome to the exciting world of proteins and enzymes! Demonstrate the diverse scientific studies encompassing the chemical processes of living things. Essential life processes that may be understood using biochemical principles include cell signaling, energy and metabolism, and genetics. This set of three demonstrations teaches students about the biochemistry occurring in their own bodies.• pH and Protein Solubility—Any change in the pH of a protein’s environment will reflect changes in the three-dimensional structure of the protein. Examine the effect of pH on the solubility and structure of casein to find its optimum value.• Digestive Enzymes at Work—Observe the biochemistry of digestion and learn how the body transforms the food we eat into essential nutrients needed to carry out cell processes and growth.• The Floating Catalyst—An enzyme may make a chemical reaction occur a million times faster than it would in the absence of a catalyst. Investigate the reaction of catalase, which catalyzes the decomposition of hydrogen peroxide in plant and animal tissues.Includes enough materials to perform each of the above demonstrations three times. This kit also comes with the Flinn Scientific ChemTopic™ Lab manual, Vol. 20, Biochemistry—The Molecules of Life, which contains instructions for four experiments and five demonstrations.
