What is formed when maltose is hydrolysed?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Two molecules of glucose
Maltose is a disaccharide made of two glucose units, so on hydrolysis it gives two molecules of glucose.
Why the other options are incorrect
Option (2) One molecule of glucose and one molecule of fructose — Incorrect. These are the products of hydrolysis of sucrose (cane sugar).
Option (3) Two molecules of fructose — Incorrect. No common disaccharide such as maltose, sucrose or lactose is made of two fructose units.
Option (4) One molecule of glucose and one molecule of galactose — Incorrect. These are the products of hydrolysis of lactose (milk sugar).
