Amino acids also contain an organic R- group that defines the properties of the amino acid.
R-groups classify amino acids into different categories such as non-polar, polar, acidic and basic.
The carboxyl group of an amino acid combines with the amino group of another amino acid to form a covalent amide bond or a peptide bond.
Amino acids form polypeptides by the formation of peptide bonds.
