Cholesterol is derived from the Ancient Greek word chole meaning bile, stereos meaning solid and -ol for alcohol. It is an organic compound and is a type of lipid as it is a sterol. It is also an important structural component of the animal cell membrane and can be biosynthesised by all animal cells.
It is also known as cholesterin and cholesteryl alcohol. The property value of hydrogen bond donor and hydrogen bond acceptor are 1 and 1 respectively and the rotatable bond count is 5.
