Question

Identify disaccharides among the following:

(a) Stachyose (b) Lactose
(c) Maltose (d) Raffinose

• A. $a,b$
  
• B. $d,e$
• C. $b,e$
• D. $b,c$

Answer 1

The correct option is D $b,c$

Stachyose: Tetrasaccharide consisting of two galactose units, one-glucose unit, and one fructose unit.

Lactose: Disaccharide sugar derived from galactose and glucose.

Maltose: Disaccharide formed from two units of glucose.

Raffinose: Trisaccharide composed of galactose, glucose, and fructose.

Hence, option D is correct.
