Quitay Morris Jake N. Professor Rafie Paz ENGL 1013 July 29 2013 Why are Teenagers so Lazy Today? The youth is the hope of the nation. That is the sentence that defines what the teenagers’ worth to the country is. We are supposed to change what the country is now. But the question is . . . Can we? From what I observed is happening now‚ instead of being the country’s biggest hope‚ we seem to be one of its burdens. There’s pre-marital sex‚ prostitution‚ juvenile delinquencies‚ and the list

Synthesis of benzilic acid from benzoin utilizing a multi-step reaction. Names: Arian Karim TA Name: Sayantan Das Lab Day & Time: Thursday 7:30-11:40 Lab Section #: Abstract The main purpose of this experiment was to synthesize benzilic acid from benzoin. This requires a multistep synthesis with benzyl as an intermediate product. The first step required HNO3 as an oxidizing agent and the second step required KOH and HCl. The percentage yields of benzil and benzilic acid were 59.5%

Protein synthesis is one of the most fundamental biological processes. To start off‚ a protein is made in a ribosome. There are many cellular mechanisms involved with protein synthesis. Before the process of protein synthesis can be described‚ a person must know what proteins are made out of. There are four basic levels of protein organization. The first is primary structure‚ followed by secondary structure‚ then tertiary structure‚ and the last level is quaternary structure. Once someone understands

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

receptor protein and a number of other proteins needed for lipid synthesis.(3) The second promoter of cholesterol synthesis is the hormone insulin. 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)

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

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.
