A disaccharide is formed when two monosaccharides react by ________ reaction.

  • A
    polymerization
  • B
    hydrogenation
  • Correct answer
    C
    condensation
  • D
    isomerisation

Solution

A disaccharide is formed when two monosaccharides are joined together by a glycosidic linkage.

This linkage is formed by the loss of a water molecule from the two monosaccharides.

Reactions in which two molecules combine to form a larger molecule with the elimination of a small molecule such as water are known as condensation reactions.

Answer: condensation

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