Glycosidic linkage between C 1 of α -glucose and C 2 of β -fructose is found in

Options

  1. AMaltose
  2. BSucrose
  3. CLactose
  4. Damylose

Correct answer

B. Sucrose

Step-by-step solution

Sucrose Sucrose is composed of a molecule of glucose joined to a molecule of fructose by an α - 1 ,   β - 2 -gIycosidic linkage. Mannose is a sugar monomer of the aldohexose series of carbohydrates. It is a C - 2 epimer of glucose. Fructose, or fruit sugar, is a ketonic simple sugar found in many plants, where it is often bonded to glucose to form the disaccharide sucrose. Lactose is composed of a molecule of galactose joined to a molecule of glucose by a β - 1 ,   4 -gIycosidic linkage. It
