Which of the following is a trisaccharide?
- A Stachyrose
- B Sucrose
- C Raffinose
- D Ribose
Answer & Solution
Correct Answer
(C) Raffinose
Step-by-step Solution
Detailed explanation
On hydrolysis stachyrose gives four, sucrose gives two raffinose gives three and ribose gives no molecule, of monosaccharides. Thus, only raffinose is a trisaccharide.
