Amino Acids
Amino acids are the monomers that form the polymer called polypeptides or proteins.
Proteins in humans and other organisms are built from a collection of 20 alpha-amino acids.
An alpha-amino acid contains a chiral carbon that is bound to an amino group (-NH2), a carboxyl group (-COOH), a hydrogen atom and an R-group (side chain).
Aspartate and glutamate are negatively charged due to the carboxylate ion group.
