Amylopectin is composed of:

Options

  1. Aβ - D - glucose , C 1 - C 4 and C 1 - C 6 linkages
  2. Bα - D - glucose, C 1 - C 4 and C 2 - C 6 linkages
  3. Cα - D - glucose, C 1 - C 4 and C 1 - C 6 linkages
  4. Dβ - D - glucose, C 1 - C 4 and C 2 - C 6 linkages

Correct answer

C. α - D - glucose, C 1 - C 4 and C 1 - C 6 linkages

Step-by-step solution

Amylopectin is insoluble in water and constitutes about 80-85% starch. Amylopectin is a water-soluble polysaccharide and highly branched polymer of a-glucose units found in plants. It is one of the two components of starch, the other being amylose. Amylopectin bears a straight/linear chain along with a number of side chains which may be branched further.
