Question

Which of the following statements are correct about glycosidic bonds in carbohydrates? a. The glycosidic bond in maltose is hydrolyzed by people who are lactose intolerant. b. A glycosidic bond links glucose and fructose together to form sucrose. c. A glycosidic bond is an ether linkage, but all ether linkages are not glycosidic bond. How do we calculate the overall free-energy change of a process consisting of two steps? During glycolysis a is converted to pyruvate. Do you think this process produces an increase or the Entropy of the system? Explain your answer.

Explanation / Answer

Regarding to the glycosidic bond all the given statements are correct.

Glycosidic bond is formed by the loss of a water molecule between two monosacharide units linking them through - O- bond called glycodic bond.So, a glycosidic is a type of ether bond.

Alpha - D- glucose and Beta - D - Fructose link throug a glycosidc bond by the loss of a water molecule from C1 of Alpha - D- glucose and C2 of Beta - D - Fructose to form a disaccharide called sucrose.
