Hello aspirant,

No, it is not possible. The glycosidic linkage formed is between two -OH groups, each of glucose and fructose. The numbering given is the same. The orientation of the molecule in the book is printed in such a way so that the reader can understand the glycosidic linkage formed from the C2 of the beta fructose. Hence, there is no change in the numbering.

I hope this information helps!

Thank you!
