Aspirin Synthesis Introduction Out of all the pharmaceutical drugs in the worlds‚ aspirin is made the most. Any potential pharmacist must be familiar with synthesizing the drug. The goal of this lab is to synthesize as much pure aspirin as possible. The reactants‚ acetyl anhydride and salicylic acid‚ must react in phosphoric acid. With phosphoric acid as a catalyst‚ the reaction yields aspirin and acetic acid. The equation for the reaction is as follows: “(CH3CO)2O + HOC6H4COOH □(→┴yields ) CH3CO2C6H4CO2H

use throughout the body. The liver is essential for monitoring and maintaining a relatively constant level of glucose in the bloodstream‚ hence the liver is involved in glycogen breakdown and synthesis because these pathways allow the liver to remove glucose from the bloodstream for glycogen synthesis when blood glucose is high and to release glucose into the bloodstream from glycogen breakdown when blood glucose levels are too low. Glycogen provides an additional source of glucose besides that

Effects of Differentiation on Enzymatic Activity Introduction HL-60 cells are capable of undergoing differentiation to induce different cell types. HL-60 cells can undergo morphological changes‚ changes in gene expression‚ and changes in protein synthesis. In the past weeks‚ we were able to conclude that HL-60 cells treated with DMSO and HL-60 cells treated with PMA will differentiate into granulocytes and monocytes upon treatment (1). We were also able to observe that both types of treated cells

The structure and synthesis of TPC is outlined in Scheme 1. Briefly‚ the compound 1 was synthesized as per literature procedure. 2 was synthesized by reacting 1-methy pyrazole-4-boronic pinacol ester with 1 by suzuki-coupling‚ the final product TPC was synthesized by treating with malononitrile in the presence of piperidine as a base and ethanol as solvent. The detailed synthesis procedure given in the experimental section. The structure and purity of TPC was unambiguously confirmed by 1H and 13C

Racism has provoked inequality among Americans for centuries. Although it has been claimed to have dissolved‚ racism is still apparent in the very set up of our nation. It pulls apart the unity of our nation by forming groups that in time will break the equality and freedom given in America. The ideal of racism still exists in today’s society‚ having found new ways to insert itself into our everyday life. As segregation and slavery have faded from American culture it is socially accepted that‚ with

What does it really mean to be a man or a woman? Masculine or feminine? Different cultures and communities have assigned certain characteristics and attributes which define each sex. But do these traits describe every man and woman’s behavior? Individuals should have the free will to act in any way they wish to‚ whether in favor of society measures or in favor of their own conscience. Throughout the course of history‚ men have been viewed and perceived to be chivalrous‚ audacious‚ dauntless‚ and

Mechanism of chalcone formation Kinetic studies have been reported for the base-catalyzed formation of chalcone and its derivatives. [7‚ 8‚ 9] Two alternative mechanisms have been advanced for the reaction of benzaldehyde with acetophenone in the presence of a basic catalyst. 5 The formation of chalcone by the acid catalyzed condensation of acetophenone and benzaldehyde has been studied [10]. The following mechanism seems to be operating- 6 Importance of chalcones [1]They have close relationship
