Metabolite Identification
Common Namebeta-Lactose
Descriptionbeta-Lactose, also known as galb1-4GLCB or b-D-lactose, 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. Based on a literature review a significant number of articles have been published on beta-Lactose.
