The subunits of proteins are called amino acids. Amino acid molecules are smaller than protein molecules and are inside of the protein molecules.

Amino acids are joined together by peptide bonds where the -COOH group and the -NH2 group of two consecutive amino acids bond with the loss of a water molecule. The sequence of the amino acids make up the primary structure of the protein.
Proteins are made of amino acids.
