Which one of the following represents the correct structure of...

Which one of the following represents the correct structure of cellulose?Which one of the following represents the correct structure of cellulose?

Options

  1. ABranched, α(1,4)\alpha(1,4) and β(1,6)\beta(1,6) - glucose
  2. BUnbranched, α(1,6)\alpha(1,6) - glucose
  3. CBranched, α(1,4)\alpha(1,4) - glucose
  4. DUnbranched, β(1,4)\beta(1,4) - glucose

Correct answer

D. Unbranched, β(1,4)\beta(1,4) - glucose

Step-by-step solution

Cellulose has a straight chain polysaccharide composed only of β−D\beta-\mathrm{D}. The β−D\beta-\mathrm{D} glucose. These β−D\beta-\mathrm{D} glucose units are linked together by C1−C4\mathrm{C}_1-\mathrm{C}_4 glycosidic linkage. The structure is shown below: Which one of the following represents the correct structure of cellulose?
