Detailed explanation-1: -Raffinose can be hydrolyzed to D-galactose and sucrose by the enzyme -galactosidase (-GAL), an enzyme which in the lumen of the human digestive tract is only produced by bacteria in the large intestine. -GAL also hydrolyzes other -galactosides such as stachyose, verbascose, and galactinol, if present.
Detailed explanation-2: -They are formed from sucrose with the ensuing addition of galactose moieties donated from galactinol. RFOs are abundant in plants and serve as desiccation protectant in seeds, as transport sugar in phloem sap and as storage sugars.
Detailed explanation-3: -Raffinose (a trisaccharide) on hydrolysis gives three monosaccharides, galactose, glucose, and fructose.
Detailed explanation-4: -Galactose: A monosaccharide found naturally in milk and dairy foods, galactose combines with glucose to form the disaccharide lactose.
