Abstract
Use of the 3,5-dinitrosalicylic acid reagent allows the simple and rapid quantification of reducing sugars. The method can be used for analysis of biological samples or in the characterization of enzyme reactions. Presented here is an application of the method in measuring the kinetics of a glycoside hydrolase reaction, including the optimization of the DNSA reagent, and the production of a standard curve of absorbance and sugar concentration.
