4-Methylumbelliferyl-alpha-L-Fucopyranoside

4-Methylumbelliferyl-alpha-L-fucopyranoside is a fluorogenic substrate for alpha-L-fucosidase. Upon enzymatic cleavage by alpha-L-fucosidase, 4-methylumbelliferone (4-?U) is released and its fluorescence can be used to quantify alpha-L-fucosidase activity. 4-?U displays excitation/emission maxima of 350/440 nm, respectively.Formal Name: 7-[(6-deoxy-alpha-L-galactopyranosyl)oxy]-4-methyl-2H-1-benzopyran-2-one.
