Individual Application: Cholesterol a) The shape of cholesterol is that it’s composed of three different fragments, a hydrocarbon tail, four steroid (hydrocarbon) rings, and a hydroxyl group. Since the hydroxyl group is polar, and the hydrocarbon rings and hydrocarbon tail are non-polar, it makes the molecule amphiphilic. The size of cholesterol varies between what types of cholesterol that is being observed. The two types of cholesterol found in the blood are low-density lipoprotein (LDP, the ‘bad’

TEN NATURAL WAYS TO CONTROL YOUR CHOLESTEROL Most doctors will tell you that high cholesterol is very bad for you; it clogs your arteries and eventually may lead to heart disease or stroke. What they don’t always tell you is that there are two types of cholesterol: LDL (Low-density lipoprotein) and HDL (High-density lipoprotein). • LDL is usually referred to as ‘Bad’ cholesterol. It can build up on the walls of your blood vessels (plaque) narrowing them and blocking blood flow to and from the

Cholesterol is a steroid alcohol that is constituted as a nonsaponifiable lipid. All steroids play an important role in the secretion of blood in which is vital for the human body to function properly. The carbon-carbon double bond in cholesterol makes the molecule as a whole immensely more reactive than other alkanes. Cholesterol’s ability to be reactive allows it to be capable of undergoing addition reactions because the pi bond electrons can easily bond to other atoms. The addition of a halogen

Low-density lipoproteins (LDL), known as bad cholesterol, are carrier vesicles that transport cholesterol in the bloodstream. Receptor-mediated endocytosis refers to system in which these LDL bind to receptors, which engulf the ligand into the cell (Alberts, et al., 2010). A protein-coding gene called proprotein convertase subtilisin/kexin type 9 (PCSK9) helps regulate the number of low-density lipoprotein receptors (LDLR) located on the plasma membrane of a cell (Duan, et al., 2012). This, in turn

composition. (plasma, buffy coat, and hematocrit). Plasma- contains the lipids and the cholesterol Buffy coat- aids with clotting cells Hematocrit- the red blood cells 3. What is dyslipidemia? What factors can influence dyslipidemia? Dyslipidemia is the abnormal amount of blood and lipoprotein concentrations. Dyslipidemia is influenced by the elevation in low density lipoprotein cholesterol (negative cholesterol LDL) or the triglyceride concentrations. Lastly, when

Benefits of Waxing for Bodybuilders: At present waxing is most popular with athletes like swimmers, gymnasts, bodybuilders, tennis players and men who are generally into fitness. Since they work hard to have lean muscular bodies, they want their musculature to show, and hair almost completely hides any definition, particularly with the abdominal muscles. Actors and models like waxing because they find if they have a hairy body they tend to be cast only in “stupid, brutish” character roles, because

Lipids are an essential macromolecule found within the body and it has many structures and has a number of functions within the body. Cholesterol is a type of lipid, which is responsible for the structure of the plasma membrane in the cell. They provide a barrier between the cell and the cell’s external environment (Alberts, 2004). Cholesterol is moved around the body through two mechanisms: Low-density lipoproteins and high-density lipoproteins. High levels of LDH can cause cardiovascular disease

Chapter 5: Cell Membranes Homework 1. The phospholipid bilayer is selectivity permeable which means that the membrane allows only some substance to cross more easily than others. This is a stable boundary because of the hydrophilic and hydrophobic regions. Hydrophilic means that a substance loves water. The head of the phospholipid faces towards the water inside/outside of the cell. The middle layer of the membrane consists of the hydrophobic region. They form the lipid tails and they hate water

Every couple of weeks or so, you hear stories of professional athletes having their sport taken away from them, because of the drive to be the biggest, strongest and best they could be. Due to this drive, they begin to use Performance Enhancing Drugs. PED’s are a danger to athletes and their health, and they should remain banned. Some of these dangers are cardiovascular difficulties, dangerous side effects, and illness in the liver. First off, the use of performance enhancing drugs can cause

Why is it important to control plasma lipid levels? Describe the mechanism of action of cholestyramine and lovastatin. It is important to control plasma lipid levels because a decrease in plasma concentration of LDL-cholesterol can decrease the risk of coronary heart disease. Cholesterol is transformed to bile acids in the liver. Then, the bile acids are excreted into the intestine, where they are reabsorbed. Cholestyramine is a large, insoluble, and positively charged resin, which binds to the negatively

I. Introduction: a. Attention Getter: Nothing can be as satisfying and enjoyable as eating junk food. Is it not? It can be so good! Food is what makes us who we are. It affects the shape of our bodies and it helps us grow into adults in a good and bad way. b. Reason to Listen: Unfortunately, not all food is good for us. These types of food are known as junk food. We all know the term “junk food” but what is the actual definition of junk food you may ask? Junk food is an informal term applied to foods

The average ratio of total cholesterol to HDL cholesterol (good cholesterol) is about 4.5. If this ratio doubles or reaches 7, you double your chances of developing coronary heart disease. You reduce that risk by as much as 50% if your ratio is 3 or lower. The lowdown on cholesterol: not all cholesterol is bad. You have the good one (HDL-1 and HDL-2), the not so bad one (VLDL) and the harmful one (LDL). To get your ratios, divide the total amount of your cholesterol by your amount of HDL. The lower

used for lowering cholesterol in people who are suffering with hypercholesterolemia to reduce the risk of cardiovascular disease. Lovastatin is a naturally occurring compound found in low concentrations in food such as oyster mushrooms, red yeast rice and Pu-erh. History # : Compactin and Mevacor, natural products with a powerful inhibitory effect on HMG-CoA reductase, were discovered in the 1970s, and taken into clinical development as potential drugs for lowering LDL cholesterol. # : In 1982, some

In 1959, Winstrol was created and was one of the very first anabolic steroids, derived from dihydrotestosterone (DHT). The UK company, Winthrop Laboratories was the first to release Winstrol on prescription, but the company was later acquired by a U.S. Sterling for manufacture and distribution. Although marketed as Winstrol, the active ingredient was Stanozolol which was approved by the FDA as safe for use within humans. At the time Stanozolol an anabolic steroid under the brand name of Winstrol
