Abstract: This experiment synthesized H-Gly-Phe-OH dipeptide using “Fmoc chemistry”. The first part of experiment was the synthesis of L-phenylalanine methyl ester hydrochloride. The methyl ester can be synthesised by reaction of thionyl chloride‚ SOCl2 and dry methanol with L-phenylalanine under reflux condition. The peptide bond was formed later in the experiment‚ where HBTU‚ DiPEA and a solution of Fmoc-Gly-OH in DMF were added to a solution of L-phenylalanine methyl ester hydrochloride in DMF

Racism can be “defined as the hatred of one person by another or the belief that another person is less than human because of skin color‚ language‚ customs‚ place of birth or any factor that supposedly reveals the basic nature of that person. It has influenced wars‚ slavery‚ the formation of nations‚ and legal codes” (“What”). The face of racism over the past 50 years has changed but yet‚ some still stay the same. People made laws against racism and it is not as blunt anymore. But opinions and stereotypes

Experiment # 3 Acetylsalicylic Acid Introduction: The purpose of this experiment is to create and isolate pure acetylsalicylic acid from the substances salicylic acid and acetic anhydride. Then one will find the melting point to determine purity. Procedure: Make a hot bath. Weigh some salicylic acid and place in conical vial. Add .480mL of acetic anhydride and a drop of concentrated phosphoric acid. Drop in a magnetic spin vane and attach air condenser to vial. Partially submerge it in
