The structure of D-glyceraldehyde is

Which of the following sugars is a disaccharide?Group of answer choicesfructosesucrosegalactoseglucose

O-linked D-mannose can form a glycosidic bond with any sugar that has a free anomeric carbon. Therefore it could theoretically form a glycosidic bond with all of the following sugars EXCEPT:A.galactose.B.ribose.C.lactose.D.sucrose.

is Maltose formed by a ɑ1-4 glycosidic linkage between two D-glucose molecules
