Question

although lactose exist in two anomeric forms.no anomeric forms of sucrose reported.why ?​

Answer 1

Answer:

Unlike the other disaccharides, sucrose is not a reducing sugar and does not exhibit mutarotation because the glycosidic bond is between the anomeric carbon of glucose and the anomeric carbon of fructose.

Answer 2

Because lactose contains a free anomeric carbon, enabling it to equilibriate into the anomeric forms of the sugar. Sucrose, has no available anomeric carbons, therefore, it cannot.
