Application

4-Methylumbelliferyl α-D-galactopyranoside has been used as an artificial substrate to assay α-galactosidase-A activity.

Biochem/physiol Actions

4-Methylumbelliferyl α-D-galactopyranoside is a fluorogenic substrate for α-galactosidase-A. The enzyme converts the substrate to form a blue fluorescent product, methylumbelliferyl. The fluorescence is measured spectrophotometrically.

Preparation Note

4-Methylumbelliferyl α-D-galactopyranoside is soluble in water (50 mg/ml), yielding a clear, colorless to faint yellow solution with the application of heat.
