How many aldose, ketose and furanose and pyranose units are present in maltose?

Options

  1. A0 aldose, 2 ketose, 0 furanose, 2 pyranose
  2. B1 aldose, 1 ketose, 1 furanose, 1 pyranose
  3. C2 aldose, 0 ketose, 0 furanose , 2 pyranose
  4. D2 aldose, 0 ketose, 1 furanose, 2 pyranose

Correct answer

C. 2 aldose, 0 ketose, 0 furanose , 2 pyranose

Step-by-step solution

Monomer of maltose is α -D-glucopyranose. It is disaciharide, so 2 aldose in 2 pyranose forms are present in maltose.
