1. Cholesterol

   Cholesterol is any of a class of certain organic molecules called lipids. It is a sterol (or modified steroid), a type of lipid. Cholesterol is biosynthesized by all animal cells and is an essential structural component of animal cell membranes. When chemically isolated, it is a yellowish crystalline solid. Cholesterol also serves as a precursor for the biosynthesis of steroid hormones, bile acid and vitamin D. Cholesterol is the principal sterol synthesized by all animals. In vertebrates, hepatic cells typically produce the greatest amounts. It is absent among prokaryotes (bacteria and archaea), although there are some exceptions, such as Mycoplasma, which require cholesterol for growth.François Poulletier de la Salle first identified cholesterol in solid form in gallstones in 1769. However, it was not until 1815 that chemist Michel Eugène Chevreul named the compound "cholesterine".

1. cholesterol

   Cholesterol is a waxy, fat-like substance that's found in all the cells of the body. It is a type of sterol which is produced naturally by the body, primarily the liver, to maintain the integrity of its cell membrane, produce hormones such as testosterone, estrogen and adrenal hormones, generate vitamin D, and produce bile acids, which help in digestion and absorption of fats. Some cholesterol also comes from the diet. However, high levels of cholesterol, particularly low-density lipoprotein (LDL), or 'bad cholesterol', in the blood can lead to plaques forming on the artery walls, which can lead to heart attacks, strokes, and other health problems.

1. Cholesterol

   Cholesterol, from the Ancient Greek chole- and stereos followed by the chemical suffix -ol for an alcohol, is an organic molecule. It is a sterol, and an essential structural component of animal cell membranes that 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. It is almost completely absent among prokaryotes, although there are some exceptions such as Mycoplasma, which require cholesterol for growth. François Poulletier de la Salle first identified cholesterol in solid form in gallstones in 1769. However, it was not until 1815 that chemist Michel Eugène Chevreul named the compound "cholesterine".

1. cholesterol

   A molecule.

   Since cholesterol is essential for all animal life, each cell synthesizes it from simpler molecules, a complex 37-step process that starts with the intracellular protein enzyme HMG-CoA reductase.
