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)

Protein synthesis is the process whereby proteins are produced‚ or synthesized‚ in living things according to "directions" given by DNA (deoxyribonucleic acid) and carried out by RNA (ribonucleic acid) and other proteins. As suggested earlier‚ this is an extraordinarily complex process that we do not attempt to discuss here. Following synthesis‚ proteins fold up into an essentially compact three-dimensional shape‚ which is their tertiary structure. DNA contains the instructions for a cell’s structure

Formal Report no. 1 Synthesis of Aspirin Chemical Principles Aspirin is most widely sold over-the-counter drug. It has the ability to reduce fever (an antipyretic)‚ to reduce pain (an analgesic)‚ and to reduce swelling‚ soreness‚ and redness (an anti-inflammatory agent). Much of this is believed to be due to decreased production of prostaglandins and thromboxanes. Aspirin’s ability to suppress the production of prostaglandins and thromboxanes is due to its irreversible inactivation of the cyclooxygenase (COX)

Lab 3: Grignard Synthesis Objective: The goal of this lab is to synthesize a Grignard reagent from bromobenzene and magnesium metal in diethyl ether. This same Grignard reagent would then be used to prepare a tertiary alcohol and then purify and characterize the product. Table of Reagents: Name Chemical formula Melting Point Boiling Point Density Safety Hazards Diethyl ether C4H10O -116.3°C 34.6°C 0.7134 g/ml Flammable Bromobenzene C6H5Br -30.6°C 156°C 1.5 g/ml

showing pride not only for the team but for the tribe as well. The on going fight with professional sports teams‚ college sports teams and even high school teams about whether or not the team mascot is racist should just stop. The definition of racism is‚ a hatred or intolerance for another race. Which is not what these teams are doing in no way are these mascots racist. The Florida State Seminoles got the okay with the Florida Seminoles tribe to use their tribe name as a team

Experiment 2 and 3: Synthesis of Aspirin and Determination of Melting Point A. Abstract Aspirin is the common name for the compound acetylsalicylic acid‚ widely used as a fever reducer and as a pain killer. The first part of the experiment aims to synthesize aspirin from the reaction of salicylic acid with acetic anhydride with the aid of phosphoric acid as a catalyst. The second part of the experiment aims to assess the purity of aspirin through the determination of its melting point and

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.

living creatures‚ work together in a certain process that is crucial to existence: the formation of proteins. Although all species differ from each other in various ways‚ the processes by which proteins are synthesized are the same in all. Protein synthesis is a very complex process. In order to understand the process‚ there some basics that are essential for cells to create the proper proteins. DNA is a very long and double-stranded molecule that contains coding‚ through four nitrogen bases (adenine
