How are disaccharides broken down?
A
dehydration synthesis
B
Hydrolysis
C
catabolism
D
metabolism
Explanation: 

Detailed explanation-1: -As disaccharides travel through the body they are broken down into simple sugars, or monosaccharides, by a process called hydrolysis. This process is facilitated by enzymes called maltases, sucrases, and lactases. These different enzymes help to break down different types of sugars in the body.

Detailed explanation-2: -Disaccharides can be hydrolysed under acidic conditions. Polysaccharides can be hydrolysed under acidic conditions. Acid hydrolysis of disaccharides and polysaccharides produces monosaccharides by breaking the glycosidic links (ether bonds) between monomer units in the structure of the molecule.

Detailed explanation-3: -The disaccharides are broken down into monosaccharides by enzymes called maltases, sucrases, and lactases, which are also present in the brush border of the small intestinal wall. Maltase breaks down maltose into glucose.

Detailed explanation-4: -Disaccharides, such as sucrose, can be recovered from plants and used as common table sugar or “inverted” (hydrolyzed) to a mixture of glucose and fructose.

Detailed explanation-5: -During digestion, these disaccharides are hydrolyzed in the small intestine to form the component monosaccharides, which are then absorbed across the intestinal wall and into the bloodstream to be transported to the cells.
