Given below are two statements.

Statement I: Maltose has two α−D−glucose\alpha - D - glucose units linked at C1{C}_{1} and C4{C}_{4} and is a reducing sugar.

Statement II: Maltose has two monosaccharides: α\alpha-DD-glucose and β\beta-DD-glucose linked at C1{C}_{1} and C6{C}_{6} and it is a non-reducing sugar.

In the light of the above statements, choose the correct answer from the options Question: given below.

Given below are two statements. Statement I: Maltose has two α - D - glucose units linked at C _ 1 and C _ 4 and is a

Options

  1. ABoth Statement I and Statement II are true.
  2. BBoth Statement I and Statement II are false.
  3. CStatement I is true but Statement II is false.
  4. DStatement I is false but Statement II is true.

Correct answer

C. Statement I is true but Statement II is false.

Step-by-step solution

Given below are two statements. Statement I: Maltose has two α - D - glucose units linked at C _ 1 and C _ 4 and is a

Maltose is composed of two α−D\alpha - D-glucose units in which C−1C - 1 of one glucose is linked to C−4C - 4 of another glucose unit.

As there is a free aldehydic group on one of the components of the disaccharides,It is a reducing sugar.
