Q34 / 160 · TS EAMCET 2018 (04 May Shift 1) · Chemistry

Which of the following carbohydrates has a glycosidic linkage?

A
Fructofuranose
B
Glucopyranose
Correct answer
C
Maltose
D
$β - D -$ fructose

Solution

In maltose, two $d -$ glucose residues are joined by a glycosidic linkage between the $α -$ anomeric form of $C - 1$ on one sugar and the hydroxyl oxygen atom on $C - 4$ of the adjacent sugar. Such a linkage is called an $α - 1, 4 -$ glycosidic bond.

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