Example Question #3 : Carbohydrates
Which type of bond is created between carbohydrates and the sidechain amine of select asparagine residues in proteins?
Possible Answers:
Both are correct
N-glycosidic
O-glycosidic
Neither is correct
Correct answer:
N-glycosidic
Explanation:
A glycosidic bond covalently joins a carbohydrate molecule to another molecule. An O-glycosidic bond is a covalent linkage between a carbohydrate and a protein, joining a serine or threonine hydroxyl side chain and a sugar (oxygen in the bond yields "O"). An N-glycosidic linkage involves bonding of a carbohydrate and a protein, joining an asparagine side chain amide and a sugar (nitrogen in the bond yields "N"). Thus, N-glycosidic is the correct answer.
