The monosaccharides of maltose is
Options
- A-D-glucose and -D-glucose
- B-D-glucose and -D-glucose
- C-D-glucose and -D-fructose
- D-D-glucose and -D-fructose
Correct answer
A. -D-glucose and -D-glucose
Step-by-step solution
Maltose is a disaccharide formed by the condensation of two glucose units. The glycosidic linkage in maltose is formed between the C1 of one -D-glucose unit and the C4 of another -D-glucose unit. Therefore, the constituent monosaccharides of maltose are two molecules of -D-glucose. Answer: -D-glucose and -D-glucose
