Badshah Mamun:
All You Need To Know About Cholesterol


Cholesterol, from the Greek chole- (bile) and stereos (solid) followed by the chemical suffix -ol for an alcohol, is an

organic chemical substance classified as a waxy steroid of

fat. It is an essential structural component of mammalian

cell membranes and is required to establish proper

membrane permeability and fluidity.

In addition to its importance within cells, cholesterol

also serves as a precursor for the biosynthesis of steroid  hormones, bile acids, and vitamin D. Cholesterol is the principal sterol synthesized by animals; in vertebrates

it is formed predominantly in the liver. Small quantities

are synthesized in other cellular organisms (eukaryotes)

such as plants and fungi. It is almost completely absent

among prokaryotes (i.e., bacteria).

Although cholesterol is important and necessary for human health, high levels of cholesterol in the blood have been

 linked to damage to arteries and cardiovascular disease.
