Given below are two statements. Statement I: Maltose has two α - D - glucose units linked at C 1 and C 4 and is a reducing sugar. Statement II: Maltose has two monosaccharides: α - D -glucose and β - D -glucose linked at C 1 and 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.
Options
- ABoth Statement I and Statement II are true.
- BBoth Statement I and Statement II are false.
- CStatement I is true but Statement II is false.
- 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
Maltose is composed of two α - D -glucose units in which C - 1 of one glucose is linked to C - 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.
