Detailed explanation-1: -Lipids are composed of carbon, hydrogen and oxygen atoms, and in some cases contain phosphorus, nitrogen, sulfur and other elements.
Detailed explanation-2: -Lipids are insoluble in water and soluble in organic solvents. Lipids are similar to carbohydrates because they are primarily made of carbon, hydrogen, and oxygen atoms bonded together, but lipids have very different properties. Lipids are insoluble in water but soluble in organic solvents like alcohols.
