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)

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.

Maggie Torres Abstract Report: General Health Related Topic What is Neuropathy? Causes and Treatments The article that I choose to write about is based on something called Neuropathy. This is a collection of disorders that occurs when nerves of the peripheral nervous system are damaged. This is located near the nervous system outside of the brain and spinal cord. Neuropathy causes many things such as pain and numbness in the hands and feet. But this results from traumatic injuries

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
