Jewellyn G. Diola; ladyjewellyndiola@yahoo.com Abstract Synthesis of 3‚4-dihydro-3-(p-methylphenyl)-1‚2-(2h)-benzoxazine involves the nucleophillic addition of the 1 °amine group upon the carbonyly group of the salicylaldehyde‚ the reduction of imine to amine and the addition of paraformaldehyde to proceed ring closure. The experiment prepared the product through Mannich reaction‚ a multicomponent condensation synthesis between ketone‚ aldehydes‚ enols and amines. Biosynthesis of benzoaxazines

In a series of experiments regarding obeying authority‚ Stanley Milgram found that “the physical presence of an authority is an important force contributing to the subject’s obedience or defiance”. Milgram concluded from his study that the proximity of an authoritative figure plays a huge role in determining whether or not the subject carried out the experiment. Specifically in the

In an experiment by professor Philip G. Zimbardo to view actions by guards and prisoner‚ ran a semi-realistic type study. Although‚ the professor felt that in fact that it was unethical to continue as long as it did‚ he has used the data to help try to reduce the control issues found. The issues were that the guards became power crazy and push more with this new-found power. The prisoners acted poorly in their roles too. The prisoners felt that they could fight back in their roles which let the guards

1. What is the “Lucifer effect” and how was it evident in the Milgram Study? The Lucifer effect refers to a transformation of human character that causes good people to commit evil actions. The effect was seen in the experiment where the prisoners and the guards started to become hostile towards one another even though they weren’t like so before the experiment. 2. What are “shield laws” and what role did they played in the Weinstein Decision? Shield laws are laws that protect researchers from being

Insulin promotes dephosphorylation (activation of HMG-CoA reductase) which promotes cholesterol synthesis in which insulin binds to its receptor protein in the liver cell membrane and stimulate irs-1 formation.irs-1 activates HMG-CoA reductase enzyme increasing rate of cholesterol synthesis.(4) FACTORS

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.

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
