Application

3,5-Dinitrosalicylic acid (DNS) has been used to stop the reaction in in vitro α-amylase inhibition study.[1] 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[2] 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.
