but isn’t cholesterol a vital cellular component?” Nowadays‚ many people associate cholesterol with diseases and refer it to something harmful to human body; however‚ cholesterol is not all bad. In fact‚ it is one of the essential cellular components in animal cells. Figure 1 (NIGMS‚ 2011) Figure 2. (Medex UK‚ 2009) Cholesterol is a waxy

Greener Brominations Abstract In this experiment‚ trans-stilbene was brominated and debrominated with the use of three methods: bromination with pyridinium tribromide‚ bromination with hydrogen peroxide and hydrobromic acid‚ and debromination with zinc. The yields of parts A‚ B‚ and C are as follows: 68.6 %‚ 54.6 %‚ and 55.9 %. Introduction In the chemical process of bromination‚ an alkene is halogenated with bromine. Solvents that are typically used include methylene chloride and carbon

by one name‚ cholesterol. Cholesterol is commonly misunderstood in our society today. In order to better understand cholesterol‚ a simplified‚ applicable approach should be made. This essay will explore the definition and function of cholesterol‚ the difference between good and bad cholesterol‚ and the risk factors associated with cholesterol levels. Cholesterol is a type of lipid‚ or fat‚ that is produced by our liver and also found in certain types of food we eat. Cholesterol is also a sterol

Cholesterol is a soft‚ fat-like‚ waxy substance found in the bloodstream and in all your body’s cells. It’s normal to have cholesterol. It’s an important part of a healthy body because it’s used for producing cell membranes and some hormones‚ and serves other needed bodily functions. But too high a level of cholesterol in the blood is a major risk for coronary heart disease‚ which leads to heart attack. It’s also a risk factor for stroke. Hypercholesterolemia is the term for high levels of blood

Bromination of Acetanilide Objective: The objective of this experiment was to use melting point and NMR to determine which of two isomers‚ ortho or para‚ would most likely form after brominating Acetanilide through electrophilic aromatic substitution. Procedure/Observations: 1. Weigh out ~280 mg of acetanilide in a 10 mL r.b. flask with a stir bar. 2. Then‚ add 2.0 mL of glacial acetic acid using a calibrated Pasteur pipet. 3. Stir the mixture until all of the acetanilide has dissolved

Bromination of Acetanilide Introduction: Bromination of acetanilide to 4-bromoaniline was studied in this experiment. One of the most important mechanism with the reaction of aromatic compounds is the electrophilic aromatic substitution reactions(wade‚2013). The electrophilic aromatic substitution enable scientists to make substituted aromatic compounds. However‚ substitution groups affect the electrophilic substitution mechanism. A nitrogen atom attached to hydrogen is learned to be a powerful

BROMINATION OF ACETANILIDE OBJECTIVE Aim of the experiment was too brominate acetaldehyde to form p-bromoacetanilide. INTRODUCTION Acetanilide is a chemical compound with the chemical formula of C6H5NH(COCH3). It is a crystalline solid that is prepared by acetylation of analine and is widely used in the dye industry. This crystalline solid is an odourless solid chemical that has a flake or leaf like appearance. It is also known as N phenylacetamide‚ acetanil or acetanilide. Its former

This disease is called “High Cholesterol”. First off‚ what is Cholesterol? Well “Cholesterol is a sticky‚ waxy‚ fatty substance found naturally throughout your body.”1 Cholesterol is a very important substance to maintain. Doing so will prevent a lot of diseases that can cause even more damage to your body. That’s why watching what you eat can play a huge factor in your life when it comes to health. Now I will explain to you why it is important to manage your cholesterol. Why is Important to manage

Title: High Cholesterol Question: What are some of the effects of high cholesterol on the blood and on the heart and how can these effects be treated or reversed? Hypothesis: If the blood thickens and get sticky then the heart will eventually get clogged‚ creating a heart condition of disease. Introduction: --Cholesterol is generally good for the body‚ but when foods that have an exaggerated amount of cholesterol are digested‚ then it becomes a hazard to blood circulation in effect‚ damaging

Hypercholesterolemia (high cholesterol) What is high cholesterol? Cholesterol is a type of fat that is highly abundant in animal products such as red meat including burgers‚ steak‚ and sausage. The Western diet is generally high in foods that contain cholesterol. Over time‚ cholesterol and other fat begin accumulating in our blood stream a condition called hypercholesterolemia. There is good cholesterol and bad cholesterol in our blood. Good cholesterol is called HDL and bad cholesterol is named LDL. Bad
