3-Fucosyllactose

Category	Enterovirus (EV)
CAS	41312-47-4
Description	3-fucosyllactose is a trisaccharide that is lactose in which the hydroxy group at position 3 of the glucosyl moiety has undergone formal condensation with the anomeric hydroxy group of fucose (6-deoxy-L-galactose) to give the corresponding glycoside. It is one of the major fucosylated oligosaccharides found in human breast milkIt, and has a role as a human metabolite. It is functionally related to a lactose.
