Abstract

The reaction of glycine (Gly) or L-α-alanine (Ala) with inorganic sodium cyclo-triphosphate hexahydrate (P3m), Na3P3O9·6H2O, gave dipeptide [glycylglycine (GlyGly) or alanylalanine (AlaAla)] and the phosphorylated products of amino acids. Maximum yields of GlyGly and AlaAla were 17.9 and 5.6%, at pH9 and room temperature, respectively. Four kinds of dipeptide (GlyGly, AlaAla, GlyAla, and AlaGly) were produced in the reaction of P3m with the mixture of Gly and Ala.
