Role in function: Serines are quite common in protein functional centres.
WebAmino acids are the compounds or building blocks that make up peptides and proteins. Each amino acid is structured from an amino group and a carboxyl group bound to a tetrahedral carbon. This carbon is designated as the α-carbon (alpha-carbon). Amino acids differ from each other with respect to their side chains, which are referred to as R groups.
