DescriptionMelibiose, also known as isomaltose, 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. Melibiose is an extremely weak basic (essentially neutral) compound (based on its pKa).
