Cholesterol People constantly hear in the media and from health experts that we as Americans have high cholesterol, often too high to be considered healthy. But what is considered a healthy level, and what sort of problems can occur when cholesterol levels reach too high or too low? What is ‘good’ or ‘bad’ cholesterol, and what are the benefits that can be gained from them? This is meant to explain the purpose of cholesterol; the different types of cholesterol, as well as, the medical concerns and benefits of high and low levels. For starters, what exactly is cholesterol? It is actually a fat made by the liver, and is a compound of sterol that is in most body tissue, such as, blood and nerves. It is essential for many functions of the body. Cholesterol is used in the production of sex hormones, converts sunshine into vitamin D, and even provides insulation for nerve fibers. So, how could one possibly have too much cholesterol? Well, there are two types of cholesterol. While both are equally necessary; having high levels of one can be detrimental to one’s health. The first type is called LDL or low density lipoprotein. LDL is found throughout the body in the blood and nerves. It is carried out from the liver. It is considered the ‘bad’ cholesterol because when too much is carried out, it causes buildup. The second type is HDL or high density lipoprotein. HDL is said to be ‘good’ cholesterol. It helps prevent arterial disease, and carries cholesterol from the rest of the body back to the liver to be broken down or removed as waste. Having high…
described. It seems to be a last resort attempt at lowering cholesterol rather than a top competitor. All four articles collide at the idea that Zetia doesn’t necessarily benefit patients. Although it appears to lower cholesterol, Zetia may also play a role in additional plaque formation. This can lead to an increased rate of heart attacks as well as other side effects of the drug. Statins on the other hand have been known to lower cholesterol by 35-60 percent; much more than Zetia. These Statins…
Fatty and Deathly
Cholesterol, a waxy substance produced by the liver and found in certain foods, is needed to make vitamin D and some hormones, build cell walls, and create bile salts that help you digest fat. Your liver produces about 1,000 milligrams of cholesterol a day but it's hard to avoid cholesterol entirely because so many foods contain it. Too much cholesterol in the body can lead to serious problems like heart disease. Many factors can contribute to high cholesterol, but the good news…
with triglycerides other than them both being hydrophobic. All steroids are derivatives of a common structure made up of four fused carbon rings. Each steroid contains different chemical groups attached to those rings. The most common steroid is cholesterol.
Phospholipids- This class of lipids are really derivatives of triglycerides. They are composed of a glycerol molecule with two fatty acids. The third carbon contains a phosphate group and usually polar molecule. Much of the molecule is hydrophilic…
RESEARCH TOPIC: Lipoproteins
Lipoproteins are the water-soluble packages that transport lipids to the tissues. For example, cholesterol is critical for certain body functions, and is transported through the blood stream by lipoprotein. There are 4 different types of lipoprotein; some is good while others can be harmful to your health. But there are many ways you can reduce your high levels.
There are four main types of lipoprotein, Chylomicrons, Very low-density lipoproteins, low-density lipoprotein…
Cholesterol, The Good, The Bad And The Ugly
Lipids are an important role in our life for various reasons. They are our componets for our nervous system, they give us a source and store of energy. They are an important part of the membrane that surrounds every body cell, they are the basic building block from, which several hormones and bile acids are made.
Our body can synthesize most of the fat we need by…
2. What forms the “backbone” of a membrane?
3. What characteristics of phospholipids allow it to form a bilayer?

5. What role does cholesterol play in the cell membrane?
6. Describe the two main classes of proteins found in the membrane?
7. What are the important functions of the integral proteins?
8. What is the difference between passive and active transport across the membrane…
1. Blood Pressure
a. What is the normal range? The normal range varies but it is widely accepted between 120/80.
b. How your readings effect your health. My reading first were off the charts. This is alarming to me, especially since my diet and exercise habits are great. For some time now my normal blood pressure has been consistently 140-150/90 or higher over 90 +. I have seen doctors about this and even had the opportunity to…
its normal rate. It can increase risk for any blood clots damaging the blood vessels stimulating through the body. Cigarette smokers are more than ten times as likely as nonsmokers to develop Peripheral Vascular Disease (PVD). As a result, high cholesterol/blood pressure, physical inactivity, obesity, and diabetes tops the list as primary risk factors for Cardiovascular Disease.
Another effect is what smoking does to a person’s state of mind and body language. Smokers have a nervous disorder which…

eating healthy or not. Cholesterol is the focus of our discussion at this point, as if treaded carefully can help you avoid many unfortunate conditions, such as blood clots, congested arteries, heart disease, and much more.
There are two types of cholesterol we will be dealing with, and they are known as LDL and HDL.
* LDL (low-density lipoprotein cholesterol, also called "bad" cholesterol)
* HDL (high-density lipoprotein cholesterol, also called "good" cholesterol)
Our Alkene styled…
