What are amino acids?
According to biochemistry, an amino acid refers to a molecule which contains both the amine and the carboxyl group. This is most pertinent for the α-amino acids having the general chemical formula H2NCHR-COOH. Here R denotes any organic molecule. The α-carbon is the common carbon molecule, where all the carboxylate groups and the amine component are attached. The amino acids differ from one another by the attachment of side chain (the R group).
The size of amino acids varies quite a lot. The simplest amino acid is glycine, where the R group is replaced by a single hydrogen atom one of the most complex amino acids tryptophan, where the R-group is denoted by a larger heterocyclic group.
Amino acids play a major role in building the protein and act as the mediator in different bodily metabolisms. The exact amino acid content with the progression of the base molecule is the determinant of a protein. The chemical properties of the structural amino acids are the responsible factor of biological nature of the protein. Even a single change of the amino acid sequence can change the protein structure as a whole and the resultant protein will act differently.
Amino acids coalesce together to form the peptides and the peptides combine to form the polypeptides or the proteins.
Apart from forming protein, different amino acid act as a precursor of different organic molecules in our body.
