Which of the following represents the correct glycosidic linkage present in maltose?

Options

AC ₁ of -D-glucose and C ₄ of -D-glucose
BC ₁ of -D-glucose and C ₂ of -D-fructose
CC ₁ of -D-glucose and C ₄ of -D-glucose
DC ₁ of -D-galactose and C ₄ of -D-glucose

Correct answer

C. C ₁ of -D-glucose and C ₄ of -D-glucose

Step-by-step solution

Maltose is a disaccharide composed of two molecules of -D-glucose. The glycosidic bond is formed between the C ₁ of one -D-glucose unit and the C ₄ of the second -D-glucose unit. Therefore, the correct glycosidic linkage is between C ₁ of -D-glucose and C ₄ of -D-glucose. Answer: C ₁ of -D-glucose and C ₄ of -D-glucose
