2′-Fucosyllactose (2′-FL) is a fucosylated neutral trisaccharide composed of L-fucose, D-galactose, and D-glucose units. It is the most prevalent human milk oligosaccharide (HMO) naturally present in human breast milk, making up about 30% of all of HMOs. It was first discovered in the 1950s in human milk. The oligosaccharide's primary isolation technique has been in use since 1972.
