which of the following statements is not correct about cholesterol ?
A. it is an essential component of cell membranes
B. it is soluble in polar solvents
C. it is soluble in non-polar solvents
D. it is the precursor of steroid hormones

Respuesta :

Answer: The correct option is (B).

Explanation:

Cholesterol are not soluble in polar solvents

It is an organic molecule with chemical formula of [tex]C_{27}H_{46}O[/tex].

As we can see from its chemical formula unit it contains large number of hydrocarbon part.This hydrocarbon part is non polar in nature by which cholesterol molecules are insoluble in polar solvents.

Answer:

B. it is soluble in polar solvents

Explanation:

Cholesterol  are essentially found in animal cell membrane and not in plants. Generally, cholesterol are known to be non polar therefore they find it hard to dissolve in polar solvents.

A molecule is said to be polar if it possess dual charge ion that is a positive charge and a negative charge .Example of polar molecules is water, the hydrogen ion provide for the positive charge while the oxygen ion provide for the negative charges which revolves around the nuclei.

A non polar molecule has no negative or positive charge . This means that the charges are evenly distributed.

Non polar and polar molecule tends to repel each other when they miss. Since  cholesterol is non polar it lack the ability to dissolve or become soluble in polar solvent like water.
