BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Enzymes in your mouth partially break down sucrose into glucose and fructose. However, the majority of sugar digestion happens in the small intestine (5). The enzyme sucrase, which is made by the lining of your small intestine, splits sucrose into glucose and fructose.

Detailed explanation-2: -Sucrase breaks down sucrose (or “table sugar”) into glucose and fructose, and lactase breaks down lactose (or “milk sugar”) into glucose and galactose. The monosaccharides (glucose) thus produced are absorbed and then can be used in metabolic pathways to harness energy.

Detailed explanation-3: -The most common disaccharide is sucrose (table sugar), which is made of glucose and fructose.

Detailed explanation-4: -The table sugar used in everyday vernacular is itself a disaccharide sucrose comprising one molecule of each of the two monosaccharides D-glucose and D-fructose.

Detailed explanation-5: -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.
