Question

Raffinose on hydrolysis forms.
A) Glucose.
B) Fructose.
C) Galactose.
D) All of these.

Answer 1

We know raffinose may be a trisaccharide composed of galactose, glucose, and fructose. It is often found in beans, cabbage, Brussels sprouts, broccoli, asparagus, other vegetables, and whole grains.

Complete step by step answer:
We must remember that in many sorts of cereal like sugar beet, cottonseed, etc, sugar is present and this sugar present in them is named raffinose. It is often hydrolyzed into D-galactose and sucrose within the presence of an enzyme called α-galactosidase.
Raffinose may be a trisaccharide and contains galactose, glucose, and fructose.

Therefore, the option D is correct.

Additional Information:
Now we discuss about the chemical properties as,
The $RFOs$ is an $\alpha - galactosyl$ derivatives of sucrose, and therefore the commonest are the trisaccharide raffinose, the tetrasaccharide stachyose, and therefore the pentasaccharide verbascose. $RFOs$ Are almost ubiquitous within the Plantae, being found during a large sort of seeds from many various families, and that they rank second only to sucrose in abundance as soluble carbohydrates.
Raffinose may have a sort of a white crystalline powder. It is odorless and features a sweet taste approximately $10\%$ that of sucrose.
Biochemical properties:
It is non-digestible in humans and other monogastric animals (pigs and poultry) who don't possess the $\alpha - GAL$ enzyme to interrupt down$RFOs$ . These oligosaccharides pass undigested through the stomach and little intestine. Within the intestine, they're fermented by bacteria that do possess the $\alpha - GAL$ enzyme and make short-chain fatty acids also because the flatulence commonly related to eating beans and other vegetables. These SCFAs are recently found to impart variety of health benefits $\alpha - GAL$ is present in digestive aids like the merchandise Beano

Note:
We must remember that the raffinose is one among the chemicals that's converted into gas after digestion in citizenry while eating some quite vegetables like cabbage and broccoli.
