Lipids are not soluble in water because lipids are composed only of carbon and hydrogen thus because of the presence of a non polar region it produces an effect called hydrophobic, which results in the polar ends to align outwards the solvent and non polar area orient inwards apart from the polar solvent.
Thus when the lipids come in contact with the solvent, they are not insoluble in water.
Examples of lipids: phospholipids, steroids, cholesterol, waxes.
<span>False Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly. </span>
