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

CHEM3412 Synthesis of a Porphyrin Porphyrins are hetereonuclear‚ macrocyclic compounds that play an important role in living organisms. Examples include the non-protein heme portion of hemoglobin in animals whereby the lone pairs on nitrogen can bind to the oxygen-carrying iron. In plants‚ chlorophyll uses the vast conjugation to allow absorption of light for photosynthesis. The characteristic colors of porphyrins is also due to the conjugation.
