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

Synthesis of Methyl Salicylate from Aspirin Esters are a class of organic compounds. An ester compromises an organic or inorganic acid in which one or more hydroxy (OH) groups have been replaced by and alkoxy (O-alkyl) group. For example‚ the simplest ester‚ methyl formate (CHOOCH3)‚ is made up of formic acid (CHO-OH) in which the hydroxyl group has been replaced by a methoxy group (-OCH3). Similarly‚ ethyl acetate (CH3CO-OCH2CH3) is made up of acetic acid (CH3CO-OH) in which the hydroxy group

Sucrose Synthesis by D. DeWitt‚ PhD v1.5 11/10/12 Introduction | Condensation Reaction | Plant Synthesis | A. Introduction Although it might seem straight forward‚ the synthesis of sucrose‚ either as a simple condensation reaction (a.k.a. dehydration synthesis)‚ or what actually happens in plants is complicated. Before we explore sucrose’s creation‚ let’s take a look at its structure. In Figure 1‚ the space-filling model is pretty but rather useless at this point in our journey. We

Synthesis of Aspirin Name: Xuanyi Li Teaching assistant: Deirdre Zwilling November 15‚ 2009 Purpose: To synthesize aspirin‚ a common analgesic drug‚ via nucleophilic acid-catalyzed substitution reaction of salicyclic acid with acetic anhydride. The whole reaction is catalyzed by phosphoric acid. (The experiment involved three parts: The synthesis of aspirin‚ the isolation and purification of aspirin‚ and the estimation of the purity of the final product.) [pic] Procedure[1]: A mixture

Jeana Greaves Chem3301-112 June 19‚ 2013 Synthesis of Aspirin from Methyl Salicylate Introduction The synthesis of Aspirin (Acetyl Salicyclic Acid) began with methyl salicylate and sodium hydroxide as the reagent. The polar oxygen accepts the electrons from now positively charged hydrogen. The positively charged sodium disassociates leaving the hydroxide ion with a negative Scheme 1 shows the mechanisms that were demonstrated during the synthesis of Aspirin. charge that attracts to the positively

U‚ and C for the nucleotides guanine‚ adenine‚ uracil and cytosine) that directs synthesis of specific proteins‚ while many viruses encode their genetic information using an RNA genome. Some RNA molecules play an active role within cells by catalyzing biological reactions‚ controlling gene expression‚ or sensing and communicating responses to cellular signals. One of these active processes is protein synthesis‚ a universal function whereby mRNA molecules direct the assembly of proteins on ribosomes

The first synthetic sweetener‚ saccharin‚ was discovered five years prior to Dulcin. The discovery of Dulcin occurred in 1883. Approximately seven years after it’s discovery‚ J.D. Reidel‚ of Berlin‚ was able to synthesis Dulcin at a reasonable cost. Once it became possible to synthesis at a reasonable cost‚ mass production of the sweetener began. Dulcin was favored over its competitor‚ Saccharin‚ because it did not possess a bitter aftertaste. For a very brief period of time Dulcin was marketed

Synthesis Conclusion: Conclusion: As we can see‚ the sources show us that during the Enlightenment period money was very important. It shows that during the time people would do merely anything for money‚ even force their children into arranged marriages or‚ as Voltaire suggest satirically‚ sell them as a food source. Parents or even the brides and grooms themselves would arranged marriages for economic gain. This was not always the case. We have learned from She Stoops to Conquer that‚ although

Abstract – This multi-step synthesis uses aniline as the starting reagent to synthesize five compounds employing several reactions such as acetylation‚ diazo coupling‚ nitration‚ bromination‚ and hydrolysis. The isolated products were analyzed with TLC and spectral data that determined most products were pure while some had a few impurities indicated by GC‚ LC‚ and a wide melting point range was shown for products 2 and 3. The presence of water in product 2 and 7 was indicated by the IR. Acetanilide
