Cholesterol [SEP] Introduction
Cholesterol (from the Ancient Greek "chole-" (bile) and "stereos" (solid), followed by the chemical suffix "-ol" for an alcohol) is an organic molecule. 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. 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.
