Maltose on treatment with dilute H C l gives:

Options

  1. AD-Glucose
  2. BD-Fructose
  3. CD-Galactose
  4. DD-Glucose and D-Fructose

Correct answer

A. D-Glucose

Step-by-step solution

Maltose is a disaccharide which contain D-glucose as a monosaccharide. Thus, Hydrolysis of maltose with d i l   H C l gives D- glucose.
