Enzymes are biological catalysts or assistants that consist of various types of proteins that work to drive the chemical reaction required for a specific action or nutrient. They can either launch a reaction or speed it up. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). The catalase used in this experiment will come from five different sources: Spinacia

synthesize trans-9-(2-phenylethenyl) anthracene from benzyltriphenylphosphonium chloride and 9-anthraldehyde through the reaction mechanism recognized as the Wittig Reaction. The Wittig Reaction allows the chemist to synthesize phosphoranes in the lab with relative ease. A more recent and inexpensive version of the reaction is the Wittig-Horner reaction (1). ABSTRACT Georg Wittig was a German chemist and Nobel Prize winner in 1979 for the Wittig reaction (1). He was born in Berlin‚ on June 16‚

HUMAN PHYSIOLOGY REPORT DAPHNIA Aim The aim of this experiment is to investigate the effect of temperature and various substances on the heart beat of Daphnia‚ a water flea. Introduction Daphnia belongs to a group of small‚ freshwater crustaceans of the order Cladocera commonly called water fleas. They are very suitable for laboratory studies due to the nature of their transparent exoskeletons. Hence‚ it is possible to watch Daphnia hearts without dissecting them. Daphnia is ectothermic and

industrially important which is known since 1877 and also commonly practiced in organic chemistry for the synthesis of various pharmaceutical compounds [1]. Catalytic benzylation of aromatics with benzyl chloride is one of the commercially significant C-C bond synthetic reaction processes to produce benzylated aromatics such as diphenylmethane and substituted diphenylmethanes. These are key intermediates in the synthesis of fine chemicals and pharmaceuticals such as analgesic or anti-inflammatory agent

Aspirin has been a pain reliever for more than 100 years. Aspirin has been used as a remedy for many illnesses for centuries now and still more things are yet to be identified about aspirin and its uses. It was recently discovered that aspirin can be used to reduce clotting of the platelets in the blood vessels‚ thus reducing the risk of heart attack in humans. Most students in their youthful age were not able to give their heart the maximum care it deserved‚ as a result‚ it leads to heart related
