Question

One mole of stachyose on hydrolysis yields:

• A. 1 mole of glucose + 1 mole of fructose + 2 mole of galactose
• B. 2 mole of glucose + 1 mole of fructose + 1 mole of galactose
• C. 1 mole of glucose + 2 mole of fructose + 1 mole of galactose
• D. 2 mole of glucose + 2 mole of fructose

Answer 1

The correct option is A 1 mole of glucose + 1 mole of fructose + 2 mole of galactose

Stachyose is an oligosaccharide.

Stachyose is a tetrasaccharide consisting of two α-D-galactose units, one α-D-glucose unit, and one β-D-fructose unit

One mole of stachyose on hydrolysis yields one mole of glucose, one mole of fructose and two moles of galactose.

Option A is correct.
