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

The Synthesis of Aspirin Chemistry Standard Level Lab Report Data Collection and Processing and Conclusion and Evaluation Date: December 8th‚ 2011 Purpose: The purpose of this lab was to synthesize aspirin‚ determine the theoretical yield‚ compare the percent yield to the theoretical yield and test the purity of aspirin by adding Iron (III) chloride to the product. Hypothesis: I hypothesize that salicylic acid will react with acetic anhydride to produce acetylsalicylic acid (aspirin)

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

Introduction Cinnamaldehyde‚ cinnamic aldehyde or 3-phenyl-2-propenal is the major constituent of cinnamon oil‚ extracted from several species of Cinnamomum (C. verum‚ C. burmanii‚ C. cassia)‚ under the family Lauraceae‚ a group of evergreen trees. Cinnamon bark (particularly C. verum) yields 0.4-0.8% oil‚ which contains 60-80% cinnamaldehyde

Morrisons recently published last April its "Corporate social responsibility report" (CSR report‚ 2006) for the previous financial year. The report puts high regard on Morrisons’ effort to minimise the impact of its business operations on the environment. Moreover‚ the report stresses the catering of the interests of its "key" stakeholders‚ namely its customers‚ suppliers‚ colleagues and shareholders. Recalling way back before it completely took over the ownership of Safeway in 8 March 2004‚ Morrisons

result in criminal charges being filed. If carried out by individuals unskilled at chemistry they could result in serious bodily harm. 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

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

Harlem Renaissance as it was called‚ influenced future generations of black writers. And Toni Cade Bambara was one of them. The historical information mentioned above was necessary because it is important to know what period of time a writer lived in‚ it helps us to understand what influenced the writer to write and thus make us understand the stories better as the writer writes what he or she sees and feels. Toni Cade Bambara grew up in Harlem‚ so the essence of the Harlem renaissance was in her blood
