Polar lipids form bilayers spontaneously in water while non-polar lipids face towards the "non-polar" side of the cell being non water-soluble.
the polar one is less stable than the non-polar one
It just means a non-polar bond. If the difference in electronegativity between the two elements is less than .5, then it is a pure (non-polar) covalent bond.
Lipids are not soluble in water.
Lipids are held together by non polar bonds but also have a few polar bonds between carbon and oxygen. But because the rest of a lipid molecule is nonpolar this contributes little to physical properties.
Because it is non-polar itself.Remember the addage : Like Dissolves Like.Polar solvents dissolve polar solutes. And non-polar solvents dissolve non-polar solutes.
Lipids, both fats and oils, have a polar head and a non-polar tail.
A type of lipid molecule with polar and non polar regions are phospholipids. Phospholipids are a class of lipids that are a major component of all cell membranes as they can form lipid bilayers.
Lipids are soluble in non-polar solvents
Lipids are soluble in non polar solvents
In a non-polar covalent bond the sharing of electrons between the atoms is equal.This depends on the difference between the electronegativities involved in the bond; when a difference don't exist or is minimal the bond is non-polar.As an example the diatomic hydrogen bond is non-polar.

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.

All the lipids are non-polar (they have not positive and negative ions) and are soluble only in non-polar compounds. They are insoluble in water because water is a polar solvant, but are soluble in organic solvents All lipids form the covalant bond, in which they share the electrons of their atoms. In covalent bonding, the electrons cannot be removed from its original shell due to the attraction between the electrons and nucleus, but it is bound to other atom too. and form the bond between these atoms.
Lipids tend to be hydrophobic, that is they "fear" water. they are soluble in oil or non-polar solvents
