Amino acids always have two functional groups: Amine group (-NH2) and a Carboxyl group (-COOH).
The polymer formed by amino acids is called a protein.
The structure of a protein macromolecule directly affects the function that it does. In a protein, amino acids are linked together by peptide bonds. A peptide bond extracts extracts a water molecule as it joins the amino group of one amino acid to a carboxyl group.
