Cholesterol Assignment Example | Topics and Well Written Essays - 500 words

Cholesterol - Assignment Example Cholesterol bromination can be used to purify cholesterol (Barton, Miller & Young 98). In most cases, oxidation refers to the addition of the oxygen atom to a substance. However, in organic chemistry, oxidation refers to the loss of bond by carbon atom to hydrogen forming new bonds with other atoms. The overall reaction is characterized by loss of electron density hence loss of the electron. Cholesterol is capable of undergoing both autoxidation and photo-oxidation to produce oxysterols in each case. The common oxidants used for cholesterol oxidation are zinc and sodium dichromate. The first step involves the formation of the ketone, where the O double bond replaces the OH functional group. Then zinc is used to remove the bromine atoms (Stewart, Lee & Can 439). Debromination is the opposite of the bromination because it involves the removal of the bromine atoms from the organic molecule. It is one of the dehydrogenation reactions where cholesterol dibromide is boiled in the presence of alcoholic halide to produce the corresponding alkene molecule. The chemistry behind this reaction is that the bromine attached to the carbon in the alkyl bromide undergoes a reaction with hydrogen that is attached to the ÃŽ ²-carbon that releases the hydrogen bromide. The product of the reaction is the formation of a double bond between ÃŽ ± and ÃŽ ² carbon resulting into an alkene (House & Row 182). Isomerization is a process involving the transformation of a molecule into another with the same atoms but different arrangement. The new molecule is called an isomer. In the case of cholesterol, oxalic acid assists in shifting 5-Cholesten-3-one to a 4-Cholesten-3-one by shuffling of the position of the carbon-carbon double bonds. Oxalic acid provides the acidic medium that favors shifting and formation of a double bond to a new location leading to the formation of the conjugated system with the ketone group (Seager, Spencer & Slabaugh 123). Crystallization is the

Motion against Provision of Aid to Developing Nations Coursework

Motion against Provision of Aid to Developing Nations - Coursework Example They will not develop the resources they have because they know they will get aid when they need it. Secondly, most of the aid given does not accomplish its task. It is lost in corrupt deals. Governments swindle the money meant for development of infrastructure and put it into different uses other than the expected ones (Wilkinson & Pickett, 2009:350). The goal is to have the money reach the poor, but in most instances, the poor remain poorer. Thirdly, the countries giving aid will place the recipient countries under too much pressure. These countries have to change their political and economic policies to suit the needs of their donating countries, and this shows that the recipient country owes the donating country a favor (Wilkinson & Pickett, 2009:351). Fourthly, the donating countries may have it as a condition that foreign companies need to manage the funds given, denying the hosts a chance to make their decisions. Since the developing nation needs the money, it is very easy to have them agree to such terms, but it will hurt its economy owing to the amount sent abroad rather than invested in the country (Wilkinson & Pickett, 2009:352). The fifth point is that the amount of money sent or the form of aid given could benefit large-scale projects while the common citizen who can only handle the smaller projects remains a spectator. The goal is to develop the lowest earning person to become self-sufficient, but the use of aid denies them this chance (Wilkinson & Pickett, 2009:350).

My writing Learning Experience in this class -where I started from the Essay

My writing Learning Experience in this class -where I started from the beginning of the class to now - Essay Example Both strategies are concerned with collection of ideas prior to actual writing. I also learned about clustering which is considered as higher level of pre-writing because in this strategy, the ideas are inter-connected with each other. At this point, the relations of each idea are being considered. On the other hand, tagmemics involves initial analysis of the subject. It is divided among particle, wave, and field perspective. The particle is the topic or idea. The wave is the manner by which the particle was affected by time. The field is how the unit is seen in a larger perspective. These learnings helped a lot in my preparations for writing. They helped me gather my ideas prior to actual writing and plan how to relate each idea to suit my topic. I also learned how to develop effective paragraphs. I learned the importance of having an introduction and conclusion in my essays. I realized that there is a need for me to introduce the topic of my essay at the first paragraph so that my readers will be able to know at first glance where the essay would be leading. I also learned that each sentence of the paragraph must relate to one idea and that each paragraph must have some relation to the preceding paragraph so that there will be smooth presentation of ideas. As a writer, I cannot just insert paragraphs where I wanted to, but there must be some logical relationship between and among paragraphs. The The different types of definition essays were also taught in the class. Before, I thought that I could just state and include in the essay everything and anything about a particular subject just to be able to come up with a definition essay. However, in my class, I learned that there are four (4) different types of definition essay, to wit: by function, by structure, by analysis, and by contrast. A definition essay by function means that the writer has to explain

Motivating employees - Coursework Example She emphasized that being respected, being taken seriously, and being listened to are considered very crucial. In this regard, using Maslow’s hierarchy of needs, Shank’s old boss failed to meet her esteem and status needs, which are the desires for self-respect, or self-esteem. These include the desires for achievement, confidence, independence, and freedom; as well as reputation, prestige, recognition, attention, importance and appreciation. For Shank, these needs have not been previously met because of the organizations’ utter disregard for a person’s worth as a person, and not as a number, as alleged. To address these missing needs, management of these previous organizations should provide positive recognition and importance to their personnel by acknowledging good performance through rewards, appreciating inputs, promotions and recognizing exemplary work, as needed. (2) Use the Expectancy Theory and/or the Equity Theory of motivation to explain how feeling underpaid might affect the work of a Flight 001 associate and what a manager can do to increase the employees motivation. The Expectancy Theory states that motivation is a product of three variables: namely, â€Å"valence which represents how much as person wants a reward; expectancy, which refers to a person’s estimate of the probability that effort will result in effective performance; and instrumentality, which relates to a person’s estimate that performance will lead to receiving the reward† (Martires & Fule, 2000, p. 22). Feeling underpaid might affect the work of an associate in terms of perceiving that the effort exerted leading to a level of expected performance is not appropriately compensated and therefore, there is this feeling of being short changed or not being properly remunerated for the particular job. In this case, the associated would

Financial Accounting Concepts - Essay Example The higher the current ratio the greater is the company’s ability to pay its bills. It is also a tool which also helps make rational decisions in keeping with a company’s objectives. This is the reason why the bank insisted that they maintain a current ratio of 1.5. This would also enable the bank to keep a track on the company’s functioning. The accounting principle relevant here is conservatism. Conservative accounting can only cause temporary increase in the company’s earnings. The effect is temporary and the actual may differ and hence not considered a good indicator of subsequent earnings. Conservative accounting would raise questions about not only the balance sheet but also about the income statement. Accounting conservatism only helps to reduce disclosure. According to me it would he unethical to record the revenue of the new sales contract in December. It is always advisable to be honest with the bank because the relation with a bank is a long-term one. If the bank found out on its own it would reflect badly on the company and then the bank would be very cautious in all future transactions also. Manipulation may not be intended by the company but banks would be cautious in all future reporting by the company incase they found out. If the company records this revenue in December the current ration would increase. They could complete the contract in December itself and raise the bill. Once the bill is raised, whether they receive cash for it or it remains as current receivables, the current ratio goes up. In this case there is nothing wrong. But as can be seen it is already the 15th December. Would it be possible to complete the contract within this period? Besides, credit has to be given to the party so cash payments cannot be expected. But in the event that the contract is executed in January and considered in December just for the sake of reporting, it would be a false
