Which of the following is a trisaccharide?

Options

  1. AStachyose
  2. BSucrose
  3. CRaffinose
  4. DRibose

Correct answer

C. Raffinose

Step-by-step solution

On hydrolysis stachyrose gives four, sucrose gives two raffinose gives three and ribose gives no molecule, of monosaccharides. Thus, only raffinose is a trisaccharide. C 18 H 32 O 16 Raffinose + H 2 O → 3C 6 H 12 O 6
