A
molecule containing both an amine and a carboxylic acidgroup; in the 20 genetically encoded amino acids in biology, both groups
are bound to the same C. Amino acids
joined by amidebonds form peptides
and proteins;
these do not contain amino acids as
such, and are instead said to contain amino acid
residues.
Organicmolecules
that are the building blocks of proteins.
There are some two hundred known amino acids,
of which twenty are used extensively in living organisms.
