Metabolite Identification
Common NameLactulose
DescriptionLactulose, also known as lactulosum or cephulac, belongs to the class of organic compounds known as o-glycosyl compounds. These are glycoside in which a sugar group is bonded through one carbon to another group via a O-glycosidic bond. Lactulose, with regard to humans, has been linked to the inborn metabolic disorder celiac disease. Based on a literature review a significant number of articles have been published on Lactulose.
