Proteins can be formed using the 20 common amino acids. Amino acids are the building blocks of proteins, and they link together in various sequences to form different proteins.

The other options—lipids, carbohydrates, and nucleic acids—are composed of different structural units:
- Lipids are primarily composed of fatty acids and glycerol.
- Carbohydrates are made up of sugar units (monosaccharides).
- Nucleic acids (such as DNA and RNA) are composed of nucleotides.

Thus, from the provided options, only proteins are directly formed using the 20 common amino acids.
