has role lactose CHEBI:22760 1-beta-D-Galactopyranosyl-4-D-glucopyranose PMID:21403918 A glycosylglucose disaccharide, found most notably in milk, that consists of D-galactose and D-glucose fragments bonded through a beta-1->4 glycosidic linkage. The glucose fragment can be in either the alpha- or beta-pyranose form, whereas the galactose fragment can only have the beta-pyranose form.
