(protein / nucleic acid / carbohydrate / lipid)

Explanation:

Amino acids are the building blocks of proteins. The bond that forms between two amino acids is a peptide bond, which is a type of covalent bond. When two amino acids combine, they form a dipeptide and release a molecule of water (in a condensation reaction). Proteins are macromolecules made up of many amino acids linked together by peptide (covalent) bonds.

Answer:

Two amino acids unite by forming a (covalent) bond between them and releasing a molecule of (water). Amino acids form a macromolecule called (protein).
