Chemistry Question on Biomolecules
Which of the following is a trisaccharide?
A
Maltose
B
Lactose
C
Raffinose
D
Stachyose
Answer
Raffinose
Explanation
Solution
Among the given options, the trisaccharide is (C) Raffinose.
Maltose (A) is a disaccharide composed of two glucose units linked together.
Lactose (B) is also a disaccharide, consisting of a glucose unit linked to a galactose unit.
Raffinose (C) is a trisaccharide made up of one glucose molecule, one fructose molecule, and one galactose molecule.
Stachyose (D) is a tetrasaccharide composed of two galactose units, one glucose unit, and one fructose unit.
Therefore, the trisaccharide among the given options is Raffinose (C).
