Application

Diastase from Aspergillus oryzae has been used:to distinguish sulphomucins and sialomucinsto discriminate acidic mucins from neutral mucins in the lingual salivary glandsas a component of the BioVision amylase activity assay buffer solution for in vitro and ex vivo degradation assays

Biochem/physiol Actions

Diastase catalyzes the digestion of glycogen. It is useful as a reducing and stabilizing agent in the aqueous synthesis of gold nanoparticles (AuNPs).
