Detailed explanation-1: -1: Glucose and fructose combine to produce the disaccharide sucrose in a condensation reaction. Sucrose, commonly known as table sugar, is an example of a disaccharide. A disaccharide is a carbohydrate formed by the joining of two monosaccharides. Other common disaccharides include lactose and maltose.
Detailed explanation-2: -Sucrose is composed of a molecule of glucose joined to a molecule of fructose by an -1, -2-glycosidic linkage.
Detailed explanation-3: -Sucrose is a disaccharide and is composed of a glucose and a fructose molecule. When sucrose undergoes a hydrolysis reaction, it splits up into glucose and fructose.
Detailed explanation-4: -The most common disaccharide is sucrose which gives D-(+)-glucose and D-(-)-fructose on hydrolysis. Both the monosaccharides i.e. glucose and fructose are connected through the glycosidic linkage between alpha glucose and second carbon beta fructose.
