Amino Acids

Amino acids are always composed of an amino group, a carboxyl group, and an R-group. Only the R-group ever varies. 20 different amino acids can be found in living organisms. Amino acids are connected to each other during the process of translation. Covalent bonds between several amino acids are called peptide bonds.
