The correct statement`(s)` about the following sugars `(X)` and `(Y) is//are`:

A

`(X)` is a reducing sugar and `(Y)` is a non-reducing sugar.

B

`(X)` is a non-reducing sugar and `(Y)` is a reducing sugar.

C

The glucosidic linkage in `(X)` and `(Y)` are `alpha` and `beta`, respectively.

D

The glucosidic linkages in `(X)` and `(Y)` are `beta` and `alpha`, respectively.

Text Solution

Verified by Experts

The correct Answer is:
B, C
In `'X'` the glycosidic linkage is between two anomeric `C` atoms, while in `Y` it is only with one anomic carbon, the other one is free. So, `'X'` will be non-reducing while `'Y'` will be reducing. Again the glycosidic linkage in `X` is between `alpha-`fuctose, in `Y`, one of the glucose units is `alpha`.
