Description

Application

4-Hydroxybenzhydrazide has been used:

• for determining the concentration of maltose from starch digestion
• for analysis of sugars from fructan containing food hydrolysate
• in colorimetric assay for reducing sugar estimation from processed feedstuff

Biochem/physiol Actions

4-Hydroxybenzhydrazide (PAHBAH), is used for assaying α-amylase and glucoamylase activities. The assay based on PAHBAH measures non-specifically the free reducing sugar groups present in samples at 415nm colorimetrically.
