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)

Obedience is when an individual responds to an order from an authority figure. A key study that has looked into research is one carried out by Milgrams in 1963. The aim of the experiment was investigate whether ordinary people will obey a legitimate authority figure even when required to injure an innocent person. Milgrams recruited 40 male participants by advertising for volunteers to take part in his study. Each participant would be paid $4.50. The experiment consisted of one ‘real’ participant

The Perils of Obedience by Stanley Milgram‚ was an experiment done on people to study the idea of obedience. However‚ a huge part in the research was the participant’s in the study had thought that the point of the experiment was how the learner’s responded to the given requests‚ not themselves. The experimenter has two participant’s given two pieces of paper to choose one from‚ both of the pieces of paper have ‘teacher’ written on them. The learner is actually a part of the research team to help

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.

"The Perils of Obedience" was written by Stanley Milgram in 1974. In the essay he describes his experiments on obedience to authority. I feel as though this is a great psychology essay and will be used in psychology 101 classes for generations to come. The essay describes how people are willing to do almost anything that they are told no matter how immoral the action is or how much pain it may cause. This essay even though it was written in 1974 is still used today because of its historical

In his book‚ Saint Benedict really stresses the rule of Obedience. Now‚ Benedict’s definition of obedience‚ is different than our definition of obedience. Many people in today’s society think of obedience as doing what you are told‚ even if you do not agree with it. Humans want freedom and do not want people telling them what to do. Saint Benedict’s view of obedience is much different‚ and many humans still practice his form of obedience in their lives today. Saint Benedict believes that a person

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

people view just authority figures. These scholars have described group mind and its effects on society and authority in different ways. For example‚ Lessing‚ the author of “Group Minds‚” says it is dangerous for us to misunderstand our human tendency to conform because we can be blindly obedient as a result. Brooks‚ the author of “The Follower Problem‚” contends that it is an issue that many in today’s society conform to the idea that we should automatically distrust any authority figure. On the other
