Q1 / 90 · JEE Main 2021 (31 Aug Shift 1) · Chemistry

Which one of the following compounds contains $β - C_{1} - C_{4}$ glycosidic linkage ?

A
Sucrose
B
Amylose
Correct answer
C
Lactose
D
Maltose

Solution

Structure of Lactose $(C_{12} H_{22} O_{11})$

The linkage is between $C - 1$ of $β$ -Galactose and $C - 4$ of $β$ -Glucose.

Hence, the correct answer is option: 'C'.
