(3) Friedel-Crafts reaction : This type of reaction involves using a haloalkane to add an alkyl group to a benzene ring. As with the halogenation above a metal halide catalyst is needed to generate the necessary alkyl electrophile : where R=any alkyl chain e.g. CH 3 CH 2.

This reaction is catalysed by the enzyme alanine aminotransferase (ALT). Next transamination reaction is reaction of aspartate with α-ketoglutarate yielding oxaloacetate and glutamate, catalysed by the enzyme aspartate aminotransferase (AST). Both ALT, and AST are used as diagnostic markers of liver cells damage.

1.5 Some chemistry involving esters. Esters are produced by the reaction of a carboxylic acid with an alcohol and result from the formation of a new bond Because the other product is water, this type of reaction is known as a condensation reaction. (There are other condensation reactions that do not...

The synthesis of aspirin is in endothermic reaction, and by adding heat it will push the reaction for- ward to favor formation of the products. After heating the mixture for 10-15 minutes, water was added to recrystallize the product.
Meaning of aspirin medical term. What does aspirin mean? Aspirin is used to relieve many kinds of minor aches and pains—headaches, toothaches, muscle pain, menstrual cramps, the joint pain from arthritis, and aches associated with colds and flu.The purpose of this lab is to synthesise acetylsalicylic acid (aspirin) by creating a reaction between acetic anhydride and salicylic acid. This was be accomplished through the use of recrystallization.
Synthesis of Aspirin and Methyl Salicylate. The reaction type shown above may be called a condensation reaction because the small molecule H2O is eliminated from the reactants while the remaining bits of the reactants condense together to give the main product.Dec 08, 2014 · SYNTHESIS AND CHARACTERISTICS OF ASPIRIN- ACETYLSALCYLIC ACID Summary: The lab experiment was divided into parts and the synthesis of the aspirin occurred during the first week. Using 4.032g of salicylic acid 8.0mL of acetic anhydride on a hot bath the reaction was speeded up by the use of a catalyst phosphoric acid.
Therefore, aspirin and non-aspirin salicylates (for example, salsalate ) should not be used in children and teenagers with suspected or confirmed chickenpox or influenza. NSAIDs increase the risk of potentially fatal, stomach and intestinal adverse reactions (for example, bleeding, ulcers, and perforation of the stomach or intestines ).
Summary: This gene encodes a receptor for prostaglandin E2, a metabolite of arachidonic acid which has different biologic activities in a wide range of tissues. Mutations in this gene are associated with aspirin-induced susceptibility to asthma. [provided by RefSeq, Oct 2009] The purpose of this experiment was to perform a base-catalyzed hydrolysis reaction while converting oil of wintergreen to salicylic acid. The full balanced molecular equation for the salicylic acid synthesis is C 8 H 8 O 3 + 2 NaOH + H 2 SO 4 -> C 4 H 6 O 3 + Na 2 SO 4 + CH 3 OH + H 2 O. An illustrated equation showing compounds to be isolated ...
