Correct answer
BSucrose and amylose has 1, 2 - glycosidic linkage
Step-by-step explanation
(a) Both maltose and lactose have 1,4-glycosidic linkage.
(b) In sucrose, C1- of glucose is connected to C2- of fructose. In amylose, C1 of one glucose unit is attached to C4 of other glucose through -glycosidic linkage.
(c) Cellulose has 1,4--D-glycosidic linkage, but amylose has 1,4--D-glycosidic linkage.
(d) In lactose, C1- of galactose is linked to C4- of glucose.
(b) In sucrose, C1- of glucose is connected to C2- of fructose. In amylose, C1 of one glucose unit is attached to C4 of other glucose through -glycosidic linkage.
