Sarah Khan Bivins-5th April 20th‚ 2013 Protein Synthesis Every day‚ you take in an abundance of different biomolecules; one of them being proteins. Have you ever wondered how proteins are made? They don’t just grow from a tree or fall from the sky‚ they are made through a process called protein synthesis. Protein synthesis is broken up in two two steps: transcription and translation. Transcription starts inside the nucleus when the DNA is unzipped by helicase. Following that‚ the mRNA nucleotides

Experiment 2 and 3: Synthesis of Aspirin and Determination of Melting Point A. Abstract Aspirin is the common name for the compound acetylsalicylic acid‚ widely used as a fever reducer and as a pain killer. The first part of the experiment aims to synthesize aspirin from the reaction of salicylic acid with acetic anhydride with the aid of phosphoric acid as a catalyst. The second part of the experiment aims to assess the purity of aspirin through the determination of its melting point and

In ‘One Man‚ Two Guvnors’‚ there are three female characters‚ the uneven ratio of women to men perhaps suggest that the female

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)
