Glucose and Glucose
|
|
|
Fructose and Galactose

|
|
Galactose and galactose

Explanation:
Detailed explanation-1: -4: Sucrose is formed when a monomer of glucose and a monomer of fructose are joined in a dehydration reaction to form a glycosidic bond . In the process, a water molecule is lost. By convention, the carbon atoms in a monosaccharide are numbered from the terminal carbon closest to the carbonyl group.
Detailed explanation-2: -Sucrose is formed when glucose is joined to fructose by a(n) glycosidic linkage. Specifically, the glycosidic link occurs between the first carbon of an alpha-glucose and the second carbon of a beta-fructose monosaccharide. Since two monosaccharides are joined to form it, sucrose is classified as a disaccharide.
