A disaccharide that gives two molecules of glucose on hydrolysis is
Open in App
Solution
The correct option is B Maltose
Maltose is the disaccharide which is formed by the linkage of 2 glucose residues by an alpha 1,4 linkage. Upon hydrolysis, the glycosidic bond is broken and maltose yields 2 glucose residues. On the other hand, the disaccharide; Sucrose yields glucose and fructose and lactose yields glucose and galactose. So, the correct answer is option B.
