Application

3,5-Dinitrosalicylic acid (DNS) has been used to stop the reaction in in vitro α-amylase inhibition study. It has also been used for the quantitation of enzymatically released reducing sugars.

Biochem/physiol Actions

3,5-Dinitrosalicylic acid (DNS) is used in colorimetric determination of reducing sugars and to analyze glycosidase (glycoside hydrolase) activity by quantitation of enzymatically released reducing sugar. The dinitrosalicylic acid method has been compared to the Nelson-Somogi colorimetric method.
