Lomotil is a prescription drug that is often used to treat acute diarrhea. It is a combination of two different drugs: Diphenoxylate and Atropine. Diphenoxylate works by disrupting the flow of the intestinal bowels, thus preventing and eliminating frequent bowel movements. However, since Diphenoxylate has narcotic properties, taking it in large doses can lead to a sense of euphoria. This can cause the drug to be misused and abused, or sold as an illicit street dug. In order to prevent this issue…

It is believed that the first sugar cane was used by a man in Polynesia.9 In 510 BC the Emperor Darius (of what was then Persia) had invaded India where he had found, “a reed which gives honey without bees.”9. But of course it’s not 100% proven that this is true. Officially, Sucrose was discovered in India in 6 century AD by boiling cane juice.1 In 1747 Andreas Sigismund Marggra (A German scientists) was examining sugar beets when he discovered sucrose.1 Later in 1802, Franz Achard (who was a…

Identification of Unknown Carbohydrates Using Various Biochemical Techniques Practical Assessment LO1 Introduction: The experiment conducted involved subjecting six samples of unknown carbohydrates to different methods of identification, this is involved several reagents including Benedict’s reagent, Barfoed’s reagent and iodine solution, these reagents provided the investigation with credible and accurate results as the reagents stated above give good indicative results to the types of…

The synthesis started with the [3+2] cycloaddition between chiral nitrone 128 and allyl cyanide under microwave activation at 110°C in toluene to provide cycloadduct 2 in 96% yield as a single isomer (Scheme 1).The regioselectivity was identical to that observed for diverse terminal alkenes, with attack on the terminal methylene by the electrophilic carbon of the nitrone, presumably due to both steric and electronic reasons.29a-f The stereoselectivity results from the approach of allyl cyanide…

The physiological processes of a mammal are in a unique balance where any deviation from the normal can result in a pathological condition. For example, mammals require a continuous intake of nutrients to ensure that every vital process can be maintained. If these processes are not maintained; the organism will begin to absorb its own nutrients, thereby reducing the availability of resources within the organism (Odette, 2005). An organism that is absorbing its own nutrients will be unable to…

INTRODUCTION The purpose of this experiment was to demonstrate the stereochemistry of the electrophilic addition using (E)-Stilbene, a trans-isomer of ethylene. Bromine was added and reacted with (E)-Stilbene to form an alkene. A product was made with both a meso-stilbene dibromide and a d/l-stilbene dibromide, which is trans-stilbene dibromide. DISCUSSION AND CONCLUSION For the reaction to form these two different compounds with the same starting reactants, the double bond of (E)-Stilbene…

in the ring. When the reaction is carried out correctly, the product that condensed and is collected into ring of the Hickman still should be dry, free if starting alcohol and ready for analysis and determination. There is a possibility of three isomers forming, which are 1-methylcyclohexene, 3-methycycolohexene, and methylene cyclohexane. The formation of product was validated by IR spectrum. Upon adding phosphoric acid into the Hickman still, the reaction started right away. After about 15…

to take place. All successful reactions had electron donating group on aromatic nucleophile, ideal reaction temperature was -40 degrees Celsius and meta substituted compounds provided higher yields. Also products that were considered to be a single isomer were due to regioselectivity which corresponded to their starting materials as well. Unsuccessful reactions include pyrrole and pyridine derivatives in which transformation did not appear. Products of the reaction were obtained via separation,…

General Introduction Dietary lipids: Dietary lipids consist of a broad group of compounds that are soluble in organic solvents and insoluble in water. Their density is lower than water and consistency varies from liquids to solids at normal room temperature, depending on their structure and function. They are also referred as ‘Oils’ which are liquid and ‘fats’ which are solid at room temperature. Lipids are the important constituents of diet due to their higher energy value. One gram of lipid…

Weed is one of the illicit substances that is being consumed by many people for various reasons. A few people use the cannabis for amusement, whereas others use it for restorative purposes. Consequently, the Canadian Federal Government is intending to sanction cannabis use this mid-year. There has been countless upholding for the legitimization of the marijuana. However, there are others that are contradicting the endeavors to sanction the weed. To begin, marijuana contains more than 400…
