A tetrapeptide has$-\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{H}$group on alanine. This produces glycine (Gly), valine (Val), phenyl alanine (Phe) and alanine (Ala), on complete hydrolysis. For this tetrapeptide, the number of possible sequences (primary structures) with$-\mathrm{N}{\mathrm{H}}_2$group attached to a chiral center is
