4-Methylumbelliferyl 2-O-(2,3,4-Tri-O-benzoyl-α-L-fucopyranosyl)-β-D-galactopyranoside

4-Methylumbelliferyl 2-O-(2,3,4-tri-O-benzoyl-α-L-fucopyranosyl)-β-D-galactopyranoside is a compound widely employed in biochemical and enzymatic research to investigate the activities of glycosidases, particularly those involved in carbohydrate metabolism. This chemical serves as a substrate for various glycosidases, including β-galactosidases and α-fucosidases. Upon enzymatic hydrolysis, the 4-methylumbelliferyl (4-MU) fluorophore is liberated, leading to an increase in fluorescence intensity that can be quantified spectrophotometrically. The specific configuration of this compound, with benzoyl groups protecting the fucose moiety, enables the precise study of enzyme substrate specificity and binding interactions. Researchers utilize this substrate to explain glycoside hydrolase mechanisms, characterize enzyme kinetics, and screen for potential glycosidase inhibitors or activators. Additionally, it finds application in carbohydrate biochemistry studies, glycoconjugate analysis, and glycobiology research aimed at understanding the roles of glycosidases in various biological processes, such as cellular signaling, development, and host-pathogen interactions. The versatility and sensitivity of this substrate make it a valuable tool for advancing our understanding of glycosidase-mediated reactions and their implications in diverse biological contexts.
