4-Methylumbelliferyl α-D-glucopyranoside（Cat No.:R000790） is a substrate commonly used in enzymatic assays to detect and quantify α-glucosidase activity. It is a synthetic compound that consists of a glucopyranoside moiety linked to a 4-methylumbelliferone fluorophore. When acted upon by α-glucosidase, the glycosidic bond is hydrolyzed, releasing 4-methylumbelliferone. This compound exhibits strong fluorescence when exposed to UV light, allowing for the convenient and sensitive detection of α-glucosidase activity. The use of 4-methylumbelliferyl α-D-glucopyranoside in enzymatic assays has contributed significantly to the study of carbohydrate metabolism and enzyme kinetics.
