Among the following, the incorrect statement is
Options
- Acellulose and amylose has 1 , 4 - glycosidic linkage.
- Blactose contains β - D - galactose and β - D - glucose.
- Cmaltose and lactose has 1 , 4 - glycosidic linkage.
- Dsucrose and amylose has 1 , 2 - glycosidic linkage.
Correct answer
D. sucrose and amylose has 1 , 2 - glycosidic linkage.
Step-by-step solution
In amylose, 1 , 4 - glycosidic linkage is present. So, this option statement is incorrect. Sucrose has 1,2-glycosidic linkage between glucose and fructose. cellulose and amylose has 1 , 4 - glycosidic linkage. lactose contains β - D - galactose and β - D - glucose. maltose and lactose has 1 , 4 - glycosidic linkage.
