X-ray crystallography is used to see the structure of molecules. scientists have used this technique to find the structure of cholesterol, an important biological molecule. knowledge of the structure of cholesterol is because it may affect

its function

Explanation:

The structure of cholesterol determines its functions

For instance -

When the  hydrocarbon tail of cholestrol is linked to one end of the steroid and the hydroxyl group is linked to the other end it is known as sterol. The hydroxyl group forms hydrogen bonds with nearby carbonyl oxygen of phospholipid. This structure of cholestrol helps in steroid hormone synthesis and bile acid synthesis,

The tetracyclic ring structure of cholesterol maintains the  fluidity of the cell membrane.
