From Wikipedia, the free encyclopedia

Cholesterol is the principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils.[1][2]

Cholesterol is biosynthesized by all animal cells and is an essential structural component of animal cell membranes. 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.[3] Cholesterol also serves as a precursor for the biosynthesis of steroid hormones, bile acid[4] and vitamin D.
