Identify the lipid molecule that is crystallisable in nature

Identify the lipid molecule that is crystallisable in nature. Also, give the name of the disorder produced by it in the human body.

Cholesterol is a crystallisable lipid of high molecular weight which possesses 17 carbon nucleus of four fused hydrocarbon rings (cyclopentane perhydrophenanthrene) and a long side chain. Cholesterol is insoluble in water and therefore, when cholesterol level rises in blood, it tends to get deposited in the wall of arteries. This causes arteriosclerosis.
