설명

애플리케이션

4-Hydroxybenzhydrazide has been used:

• for determining the concentration of maltose from starch digestion[1]
• for analysis of sugars from fructan containing food hydrolysate[2]
• in colorimetric assay for reducing sugar estimation from processed feedstuff[3]

생화학적/생리학적 작용

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.[4]
