How do proteins differ from carbohydrates and lipids?

Solution
Proteins have polar C=O and N-H groups, so they are able to form hydrogen bonds with other molecules and with each other.A typical carbohydrate is starch, which is consists of many glucose units (C6H12O6) joined together.
Most carbohydrates are hydrophilic and soluble in water because of their polar OH groups.
Lipids are hydrophobic and insoluble in water. They have varied structures, but all have a polar "head" and a large nonpolar "tail"".
Fats and oils are typical lipids. The molecule is mostly nonpolar hydrocarbon with some polar C=O groups at one end.
