Cholesterol

Chemical & IUPAC name:

Chemical name: 10,13-dimethyl-17-(6-methylheptan-2-yl)-2,3,4,7,8,9,11,12,14,15,16,17-dodecahydro-1H-cyclopenta[a]phenanthren-3-ol

IUPAC name: CHOLESTEROL/ (3)-cholest-5-en-3-ol

STRUCTURE

Chemical Formula:

C27H46O

Functional Group:

discovered that atherosclerosis plaque from human aortas contained cholesterol in 20 to 26 times, the concentration of cholesterol found in normal aortas. The name originates from the Greek CHOLE-(BILE) and STEREOS (SOLID) and the chemical suffix- ol for an alcohol, as researchers first identified cholesterol in solid form in gallstones in 1784.

Melting Point: 148 degrees Celcius

Molar Mass: 386.65 g/mol

Density: 1.05 g/ml cube.

Boiling Point: 360 degrees Celcius

Soluble In: Acetone, Benzene, Chloroform, Ethanol, Ether,

Hexane, Isopropyl, Myristate, & Methanol

Cholesterol is required to build and maintain cell membranes; it regulates membrane fluidity over a wider range of temperatures. Also, cholesterol also aids in the manufacture of bile (which is stored in the gallbladder and helps digest fats), and is also important for the metabolism of fat soluble vitamins, including vitamins A, D, E and K.

Risks of cholesterol (health problems):

When there’s too much cholesterol in your bloodstream, the cholesterol from LDL can build up in the walls of yourarteries. Along with fats like triglycerides and other things in the bloodstream, it forms a growing “plaque” that bulges out of the artery wall and can begin to block blood flow—a process called atherosclerosis. Problems get even worse if a plaque bursts and a blood clot forms on top, which can block an artery.

Like any muscle, the heart’s own muscle needs a constant supply of oxygen and nutrients, delivered by the blood in the coronary arteries. When these arteries become narrowed or clogged by plaque, the result is coronary heart disease. If the blood supply to a portion of the heart is completely cut off, the result is a heart attack.

How to prevent bad risks:

Physical activity/exercise. Regular physical activity may lower LDL ("bad") cholesterol and raise HDL ("good") cholesterol levels.

Keeping regular check on the cholesterol level, especially for people with heart attack in disease family.

One should keep track on food they are eating and stop smoking.

Risk & Benefits:

The most important of these is its role in forming and maintaining cell walls and structures. Cells also need cholesterol to help them adjust to changes in temperature, and it's used by nerve cells for insulation. Additionally, cholesterol is essential for synthesizing a number of critical hormones, including the sex hormones testosterone, progesterone and estrogen.
