Lab Report #1 Title: Synthesis of Divanillin Abstract: The purpose of this experiment was to synthesize divanillin. This was done via the oxidative dimerization of two equivalents of vanillin‚ using enzyme horseradish peroxidase as the catalyst. Procedure: Lab Handout: Nishimura‚ R.T.; Giammanco‚ C.H.; Vosburg‚ D.A. J. Chem Educ. 2010‚ 87‚ 526-527. Discussion: Mechanism: Reaction 2 Vanillin H2O2 Divanillin 2 H2O

oxygen and water‚ as follows: 2 H2O2 → 2 H2O + O2 Although this reaction occurs spontaneously‚ enzymes increase the rate considerably. At least two different enzymes are known to catalyze this reaction: catalase‚ found in animals and protists‚ and peroxidase‚ found in plants. A great deal can be learned about enzymes by studying the rates of enzyme-catalyzed reactions. The rate of a chemical reaction may be studied in a number of ways including: • measuring the rate of appearance of a product (in this

Objectives Protein Isolation: Protein isolation for a western blot uses detergents and mechanical force to separate seeded cells from their container. Eukaryotic cells are attached to the surface of a flask by cadherins. In the past‚ we’ve separated the cells from the flask by breaking these bonds with a protease‚ but in order to keep the proteins intact‚ a different method needs to be used to extract the proteins. In protein extraction for a western blot‚ we use detergents to lyse the membrane

equilibrium shifts to counteract the change to reestablish an equilibrium. The initial conditions prior to any change can be viewed as a state of equilibrium because no reaction was occurring and therefore no products were being formed. However‚ once peroxidase was added to hydrogen peroxide‚ oxygen gas rapidly started to form and began to quickly react with guaiacol to produce tetraguaiacol in an attempt to reconstruct equilibrium. Because with every minute passing there was a larger amount of the product

build healthy collagen and promote strong immunity‚ and‚ when levels of vitamin C are low‚ the body compensates by recycling oxidized vitamin C. This is referred to as redox cycling‚ and it’s performed by the “mother of antioxidants”‚ glutathione. So long as glutathione is available‚ the vitamin C redox cycle makes do with whatever vitamin C is available from diet and supplements. And‚ thanks to Dr. John Ely‚ it can also be used as a weapon. In the 1970’s‚ Dr. John Ely proposed the (GAA) “Glucose Ascorbate
