Ethanol is an organic substance and so dissolves other organic substances; it is frequently used as an organic solvent. Preparation Note Cholesterol monohydrate yields a clear, colorless to faint yellow solution in hot alcohol. However, there are some lipids that, in modified form, have limited water solubility. It is observed that solubility increases with increase in temperature. Ethanol extracts the lipid from the crushed solid sample. Cholesterol is any of a class of certain organic molecules.A cholesterol is a sterol (or modified steroid), a type of lipid. Meat, fish, eggs, butter, cheese, and milk all have cholesterol in them. The hydrophobic interaction of the carbon in the short chain with water is not great and is overcome by the hydrogen bonding. THe hydrophilic hydroxyl group of cholesterol interacts with aqueous environment, whereas the large hydrophobic domain fits between C-tails of lipids.
