Why is cholesterol non-polar?

Answer 1

well im not 100% sure, but i know that water is polar, and only other polar things can dissolve into it. fats, i.e. cholesterol, are not soluble in water, and therefore must be nonpolar. ALSO, cholesterol is made up of four hydrocarbon rings. hydrocarbon rings, obviously, are made of hydrogen and carbon. (side note - polar compounds are formed when the difference of electromagnetivity - how much the element attracts electrons - between the elements causes an imbalance in the direction of attraction). the difference in electromagnetivity between those two elements is too little to be considered a polar molecule.

Answer 2

Although Lipids have a polar head and non-polar head, the polar head is not stongly polarised and therefore lipids are not soluble in water.

Answer 3

Lipids are called nonpolar because of the configuration of lipid molecules. Atoms in a lipid molecule share electrons equally in their bonds.

Answer 4

Because Lipids are non polar and water is polar.

Answer 5

lipids are nonpolar because they have no negative and positive poles

Answer 6

Due to their numerous C-H bonds, Lipids are nonpolar and insoluble in water. Only the ends of the fatty acids can be attracted to water.

Answer 7

Fats are covalently bonded and covalent bonds are non-polar in nature (carbon-hydrogen bond in this case)

Answer 8

Their molecules don't have a charged end.
