Lab 1: Synthesis of Aspirin Introduction: The purpose of this lab was to demonstrate the ability to easily alter the molecular structure of a compound to greatly increase its utility. In this case‚ an acetyl group was added to salicylic acid‚ a naturally occurring compound with significant pharmaceutical value. Without the addition of the acetyl group‚ salicylic acid is an irritant to the gastro-intestinal (GI) tract. Once the acetyl group is added via a simple reaction‚ acetylsalicylic

Identifying sites of protein synthesis in Chlamydomonas using erythromycin and cyclohexamide as protein synthesis inhibitors. October 16‚ 2009 Introduction: In living cells‚ prokaryotic or eukaryotic‚ the synthesis (construction) of proteins is accomplished by similar machinery. Amino acids‚ ribosomes‚ messenger RNA (mRNA)‚ and transfer RNA (tRNA)‚ are all necessary for the building of functional proteins in a cell. Ribosomes are the site of protein synthesis in a cell‚ and there are two

MDMA ("Ecstasy") is a semi-synthetic compound which can be made relatively easily from available precursors. Synthesis instructions exist which can be followed by an amateur with very little knowledge of chemistry. However‚ people with less than 2 years of college chemistry experience would probably not be capable of sucessfully synthesizing MDMA‚ and would either
