-maltose consists of

Options

  1. Aone -D-glucopyranose unit and one -D-glucopyranose unit with 1-2 glycosidic linkage
  2. Btwo -D-glucopyranose units with 1-2 glycosidic linkage
  3. Ctwo -D-glucopyranose units with 1-4 glycosidic linkage
  4. Dtwo -D-glucopyranose units with 1-4 glycosidic linkage

Correct answer

D. two -D-glucopyranose units with 1-4 glycosidic linkage

Step-by-step solution

In maltose Ist carbon atom of one -Dglucopyranose unit is linked to 4th carbon atom of adjacent -D glucopyranose unit through glycosidic linkage.
