partner and I were to conduct an experiment about the oxidation rate of the enzyme peroxidase in the presence of its substrate guiacol. Also we used other substrates‚ such as hydroxylamine an enzyme inhibitor‚ to observe the weather the reaction rate was slowed down‚ sped up‚ or stopped reactions all together. These results were recorded by taking the materials in a test tube‚ then inserting them into a spectrophotometer to record the oxidation (intensity of color change from clear to reddish-brown)

Green Oxidation of Borneol to Camphor Abstract: This lab converted borneol to camphor using a green oxidation. Sodium hypochlorite was used instead of the less “green” Jones reagent. Borneol was mixed with glacial acetic acid and oxidized with sodium hypochlorite to make crude camphor. The crude camphor was purified by sublimation. The final product was characterized by obtaining a melting point and inferred spectroscopy. The experiment was carried out to see if bleach could oxidize borneol

red. Does anyone know which functional group would be present in solution? Potassium Magante is K2MnO4 whereas the permanganate is KMnO4‚ in the second one the Mn as a higher oxidation state of +7‚ the other one just +6. It would show that a double bond is present. (It oxides the alkene to a diol‚ which changes the oxidation state of the Mn changing it’s colour) Original post by GyasiW) First of all I would like to know the differences in formulae between Potassium Mangante and Potassium Permanganate

If the oxidation number of an atom decreases in a reaction‚ it indicates a gain of electrons. • You can balance an equation by finding the coefficients that make the number of electrons lost by one atom of one element equal to the number of electrons gained

oxygen in the air. Via a free radical process‚ the double bonds of an unsaturated fatty acid can undergo cleavage‚ releasing volatilealdehydes and ketones. This process can be suppressed by the exclusion of oxygen or by the addition of antioxidants. Oxidation primarily occurs with unsaturated fats. Microbial rancidity[edit] Microbial rancidity refers to a process in which microorganisms‚ such as bacteria‚ use their enzymes such as lipases to break down fat. This pathway can be prevented by sterilization

ATP 8.1.1 State that oxidation involves the loss of electrons from an element‚ whereas reduction involves a gain of electrons; and that oxidation frequently involves gaining oxygen or losing hydrogen‚ whereas reduction frequently involves losing oxygen or gaining hydrogen. Oxidation: gain oxygen / lose hydrogen / lose electrons Reduction: lose oxygen / gain hydrogen / gain electrons 8.1.2 Outline the process of glycolysis‚ including phosphorylation‚ lysis‚ oxidation and ATP formation.

antioxidant are used widely in the production of food which fats and oils are used as raw materials and in the marketing of foods containing fats under modern conditions. The major factor in quality degradation of fats and fatty portions of foods is oxidation. In the oxidative deterioration of fats and fat-like substances‚ off-flavors and off-odors are usually reported. Rather than the breakdown of the unsaturated fat molecules‚ there are four types of fat deterioration. Hydrolysis is the formation of
