L-Fucose

L-Fucose

L-fucose is a deoxyhexose, often attached at glycan termini, forming blood-group antigens and selectin ligands, and also appearing on fucosylated human-milk oligosaccharides.

Primary

Support immune-cell adhesion recognition

Fucosyltransferases attach L-fucose to glycan termini, forming Lewis antigens and selectin ligands that affect leukocyte rolling along vessel walls. Mucosal glycocalyx and blood-group antigens use the same fucose-decorating enzymes; cells recognize one another through this terminal sugar.

Primary

Promote intestinal fucosylation ecology

Difucosyllactose among human-milk oligosaccharides has L-fucose as a characteristic residue; infant bifidobacteria can recognize and use it. Seaweed polysaccharides also often carry fucose residues. When free sugar is supplemented, change usually sits on intestinal fucosylation ecology.
