Lab Report Macrocyclic Synthesis (Heme Analog) I. Purpose of Experiment and Introduction The purpose of this lab experiment is to prepare meso-tetraphenylporphin (TPP) and its copper‚ cobalt or zinc complex by condensing benzaldehyde with pyrrole in boiling propanoic acid. II. Introduction and Background There are two types of proteins that function as oxygen carriers: myoglobin (stores the oxygen) and hemoglobin (present in red blood cells and is responsible for oxygen transport)

A Synthesis of Safrole and o-Safrole W.H. Perkin & V.M. Trikojus J. Chem. Soc. 1663 (1927) HTML by Rhodium No direct synthesis of safrole has been recorded‚ the most recent attempt being that of Baker and Robinson (JCS‚ 1925‚ 127‚ 1424)‚ who distilled the product of the action of silver oxide and water upon gamma-piperonylpropyltrimethylammonium iodide‚ but obtained isosafrole‚ the double bond moving into the position of greater stability.

In this assignment I will be identifying the main capital appraisal techniques and evaluate them by showing their strength and weaknesses. Then compare them with each other and show the main difference between them. At the end I will be showing some tables taken from different books ranking these methods and showing which methods are more used by most of the companies in the US and UK. Most of the competitive companies are looking for expansion and growth in order to control a bigger share of

Lab Report Synthesis and Characterization of Aspirin (Acetylsalicylic Acid) The Synthesis and Characterization of Aspirin (Acetylsalicylic Acid). Summary: In this experiment‚ we produced 4.21 g of acetylsalicylic acid. Our theoretical yield was calculated to be 5.22 g. Therefore our % yield was determined to be 80.6%. The experimental boiling point range of acetylsalicylic acid was found to be 130-132° C. The true melting point of acetylsalicylic acid is 135° C‚ therefore our percent

agent for rabies. The rabies virus is enveloped‚ it is covered/surrounded by a covering for protection. The rhabdovirus contains up of a helical ribonucleoprotein core(RNP)‚ and an envelope that is surrounding the viru (CDC‚2011). Eukaryotes have a synthesis process between protein and RNA that forms the ribonucleoprotein. The rabies genome has five protein components: nucleoprotein‚ phosphoprotein‚ matrix protein‚ glycoprotein‚ and polymerase protein(CDC‚2011).

Name Period Date The Synthesis of Aspirin Background Pharmaceutical research labs perform chemical reactions between organic molecules that contain mostly carbon. Since the atoms in organic molecules tend to be nonmetals‚ then the bonds that hold them together are covalent bonds. Only a few elements on the periodic table are nonmetals: C‚ N‚ O‚ S‚ Cl‚ and F. This small number of elements can be bonded together in different quantities‚ bonding types (single‚ double‚ triple bonds)‚ and structural

Introduction Performance appraisal is a method which is increasingly used to evaluate employees to determine the degree to which they are performing effectively and encourage them to direct their energies towards organizational performance. Although the appraisal is being practiced‚ there are criticisms made against the system which generally arise from within the Orthodox and radical management frame work. This essay outlines the orthodox and radical critiques respectively and suggests whether
