BACHELOR OF SCIENCE (HONS) BIOTECHNOLOGY YEAR 1 SEMESTER 1‚ 2 & 3 UDBB 1164 FUNDAMENTAL ORGANIC CHEMISTRY 0 EXPERIMENT 1 PROPERTIES OF HYDROCARBONS Introduction Hydrocarbons are compounds which contain only carbon and hydrogen‚ can be classified into several types‚ depending on their structure. Aliphatic hydrocarbons are divided into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene)

Chapter 15 COMPANY SECURITIES 15.1 DEBENTURES This is a written acknowledgement of a debt owed by a company. Whilst it is possible for some debentures to be unsecured‚ those given to the bank will usually incorporate a fixed and / or a floating charge over the company’s assets. 15.2 FIXED CHARGE This is a charge which immediately encumbers specific assets of the company. Accordingly‚ the chargee’s (bank) consent would be required if the company is to deal with or dispose the assets

focuses on separating and identifying the components of Panacetin‚ which is a common medication that relieves pain. The label reveals that Panacetin is composed of sucrose (10%)‚ aspirin (40%)‚ and Tylenol (50%). Although this information is reported‚ the true composition of Panacetin is questionable. While sucrose and aspirin are present in Panacetin‚ Tylenol may be replaced by an unknown component (acetanilide or phenacetin). Separation of the components of a sample of Panacetin may prove valuable

Aspirin Background Aspirin Aspirin‚ or acetylsalicylic acid (ASA) is a salicylate drug‚ and is generally used as an analgesic (something that relieves pain without producing anaesthesia or loss of consciousness) for minor aches and pains‚ to reduce fever (an antipyretic)‚ and also as an anti-inflammatory drug. Aspirin works by prohibiting biological substances such as prostaglandins. Many different prostaglandins exist in the human body each serving a plethora of physical functions.

describe the functioning of Aspirin in our body‚ its various properties to fight pain‚ and its evolution over the years. Littlejohn describes how Aspirin claimed celebrity status as one of the world’s most popular‚ inexpensive painkillers by relieving headaches‚ sprains‚ blows‚ burns‚ swelling and fever. Furthermore‚ she added that Aspirin could also be used to reduce the risk of stroke and heart attack. The author supports the main idea by describing how the aspirin when taken with a modest stream

Freezing-Point Depression to Find Molecular Weight Abstract: In this lab‚ the purpose was to use the freezing point depression method to determine the molecular weight of aspirin. This was done by determining the freezing of t-butanol and that of a t-butanol and aspirin solution; then finding the molality of the solution‚ and moles of aspirin. In the results of the experiment‚ the molar mass was found to be 192.2 g/mol‚ which differed from the established value of 180.2 g/mol by 6.7% error. Introduction:

BMS3021 – Research Topic: Aspirin TOPIC SUMMARY Aspirin is able to inhibit the synthesis of the Thromboxane A2 precursor‚ by irreversibly binding to the COX-1 enzyme Lack of Thromboxane A2 means that there is no signalling for platelet aggregation so there is no blood clot formation‚ leading to its ability to act as a ‘blood thinner‘ SALT found that in a low-dose of 75mg of Aspirin a day‚ secondary prophylaxis of new cardiovascular events were reduced by 16-20% By decreasing the daily dose to 75mg
