Among the following, the incorrect statement isAmong the following, the incorrect statement is

Options

  1. Acellulose and amylose has 1,4−1, 4 -glycosidic linkage.
  2. Blactose contains β−D−\beta - D -galactose and β−D−\beta - D -glucose.
  3. Cmaltose and lactose has 1,4−1, 4 -glycosidic linkage.
  4. Dsucrose and amylose has 1,2−1, 2 -glycosidic linkage.

Correct answer

D. sucrose and amylose has 1,2−1, 2 -glycosidic linkage.

Step-by-step solution

In amylose, 1,4−1, 4 -glycosidic linkage is present.
Among the following, the incorrect statement is
So, this option statement is incorrect.

Sucrose has 1,2-glycosidic linkage between glucose and fructose.
