Match List- I with List- II . List- I List- II (a) Sucrose (i) β - D - Galactose and β - D - Glucose (b) Lactose (ii) α - D - Glucose and β - D - Fructose (c) Maltose (iii) α - D - Glucose and α - D - Glucose Choose the correct answer from the options given below:
Options
- Aa → iii ,   b → ii ,   c → i
- Ba → iii ,   b → i ,   c → ii
- Ca → ii ,   b → i ,   c → iii
- Da → i ,   b → iii ,   c → ii
Correct answer
C. a → ii ,   b → i ,   c → iii
Step-by-step solution
(1) Sucrose → α - D - Glucose and β - D - Fructose (2) Lactose → β - D - Galactose and β - D - Glucose (3) Maltose → α - D - Glucose and α - D - Glucose a → II b → I c → III Sucrose is made up of two monomers α-D-Glucose and β-D-Fructose. Lactose is made up of two monomers β-D-Galactose and β-D-Glucose.
