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

Discrimination‚ which thirty years ago was barely recognized in domestic law‚ is now the subject of legal attention. This could be explained by the rapid development of trade relations‚ globalization policy and drastic change of the working environment. Although there are many discrimination laws‚ they are not always obeyed. That is why the employment

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)

Stereotypes are generalizations about a group of people we attribute as a defined set of characteristics to this group. These classifications can be positive or negative‚ such as when various nationalities are stereotyped as friendly or unfriendly. The use of stereotypes is a major way in which we simplify our social world‚ since they reduce the amount of processing‚ we have to do when we meet a new person. A good thing about stereotype is that it helps us to respond faster to situations because
