Question

Cholesterol, which is composed primarily of carbon and hydrogen atoms, is therefore

1. an acid.
2. a base.
3. insoluble in water.
4. a buffer.
5. a polar molecule.

Answer 1

Answer:

Cholesterol, which is composed primarily of carbon and hydrogen atoms, is therefore insoluble in water.

Explanation:

Cholestorol is a sort of lypid, which are insoluble in water. They are only soluble in non polar solvents.

As it is soluble in non polar solvents, it is not a polar molecule, either a buffer.

This molecule is one of the four basic molecules for life (lypds, carbon hydrates, nucleic acids and proteins)
