MCQ
Which of the following is not a disaccharide?
  • A
    Cane sugar
  • B
    Raffinose
  • C
    Lactose
  • D
    Maltose

Answer

  1. Raffinose

Explanation:

Cane sugar contains glucose and fructose so it is a disaccharide.

Lactose contains glucose and galactose so it is a disaccharide.

Maltose contains glucose and glucose so it is a disaccharide.

Raffinose contains 1 unit of glucose, 1 unit of fructose and 1 unit of galactose so it is not a disaccharide. It is a trisaccharide.
