Chapter 1 Carbon Compounds and Chemical Bonds. (Covered material: 1.1 - 1.8; 1.12 - 1.17) 1. Structural Theory – most fundamental theory of Organic Chemistry (developed independently by A. Kekule‚ A. Couper and A. Butlerov between 1858 and 1861). Organic Compounds – compounds of carbon and hydrogen. Other elements frequently found in organic compounds are: oxygen‚ nitrogen and halogens (F‚ Cl‚ Br‚ I); less frequently found are: sulfur and phosphorus. Review Periodic Table for determining valence

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

Separation of Amino Acids by Paper Chromatography Chromatography is a common technique for separating chemical substances. The prefix “chroma‚” which suggests “color‚” comes from the fact that some of the earliest applications of chromatography were to separate components of the green pigment‚ chlorophyll. You may have already used this method to separate the colored components in ink. In this experiment you will use chromatography to separate and identify amino acids‚ the building blocks of proteins

ch1. Chapter 1 describes Okonkwo’s principal accomplishments that establish his important position in Igbo society. These details alone provide insight into Okonkwo’s character and motivation. Driving himself toward tribal success and recognition‚ he is trying to bury the unending shame that he feels regarding the faults and failures of his late father‚ Unoka. Essentially‚ Okonkwo exhibits qualities of manhood in Igbo society. A Umuofian man can take as many as four titles‚ each apparently more expensive
