> <NAME>
beta-D-Galp-(1->4)-D-Xylp

> <DEFINITION>
A disaccharide consisting of a β-D-galactopyranose residue joined to a D-xylopyranose residue by a (1→4) glycosidic bond. Used to diagnose hypolactasia (lactose intolerance as a result of lactase deficiency) via presence of D-xylose after cleavage by lactase.
