This separated the DBU containing ψ from a beige precipitate that turned out to be mostly CA with some side products. The resulting supernatant was purified using reverse phase chromatography to isolate ψ as its DBU salt. Once dried‚ the crude product was ran through a cation exchange column using 0.1% formic acid to remove DBU to obtain ψ as its free acid form. Next‚ the purified compound was subjected to a Fischer esterification reaction with isopropanol to form the isopropyl

Caroline Guidry Dr. Beverly A. Clement Organic Chemistry 2423‚ Section 304 25 October 2017 Lab 6: Natural Products I The main goal of this experiment was to employ isolation techniques to derive chemicals from two different natural sources and study their properties (Clement 91). The two natural sources used in this experiment were an orange (the peel contains limonene‚ which is a terpene) and a dichloromethane solution of clove oil (which contains eugenol‚ an acetogenin). To isolate the eugenol

The purpose of this lab was to determine the effects of changes in variables such as temperature‚ pH and concentration on catalase enzyme activity. Proteins are organic compounds made up of amino acid subunits consisting of carboxyl and amino functional groups‚ linked together by peptide bonds through condensation reactions. They are an essential part of all living organisms. Enzymes are “biological catalyst used to speed up chemical reactions (Athanasopoulos‚ 2014). Normally‚ for chemical reactions;

The Synthesis of Organic Aspirin ABSTRACT: The purpose of this experiment was to find out how a reaction undergoes for a globally known painkiller called aspirin‚ and to become familiar with achieving successful yields. Aspirin is synthesized from salicylic acid and acetic anhydride. Those two chemicals are mixed together along with sulfuric acid to form a crude solid. Filtration is used separate the impurities from the crude aspirin. To get purified aspirin‚ the precipitate was heated until all

I. Introduction: The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration

Bita Heydari Lab report 3 The 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
