Chapter 8: Q24P. (page 243)

In addition to lactose, how many other heterodisaccharides can D-galactose and D-glucose form?

Short Answer

Expert verified

19 different disaccharides are formed from D-galactose and D-Glucose. D-glucopyranose forms 19 different disaccharides with their 伪 and 尾 forms. In the same manner, the D-galactose and D-glucose form 19 different heterodisaccharides for their pyranose form.

Step by step solution

01

Lactose

Lactose is a disaccharide sugar linked by one molecule of galactose and one molecule of glucose and the link is 尾 (1鈫�4).

02

Heterodisaccharides from D-galactose and D-glucose

D-galactopyranose and D-glucopyranose form 19 different heterodisaccharides.

19 different heterodisaccharides are formed by D-galactose and D-glucose.
