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;

Abstract In this piece of coursework I have been investigating the synthesis of Aspirin and checking for presence and purity of Aspirin. Throughout this coursework we have looked at the history of Aspirin; industrial manufacturing; making salicylic acid; the preparation of Aspirin; recrystallization and purity; melting point; thin layer chromatography (TLC) and titration of Aspirin. I’ve learned a lot about Aspirin‚ how it works and how it is made. We found out that the Aspirin we made and used
