The difference between amylose and amylopectin is
  1. A
    amylopectin have 1 →\to→ 4 α\alphaα-linkage and 1 →\to→ 6 α\alphaα-linkage
  2. B
    amylose have 1 →\to→ 4 α\alphaα-linkage and 1 →\to→ 6 β\betaβ-linkage
  3. C
    amylopectin have 1 →\to→ 4 α\alphaα-linkage and 1 →\to→ 6 β\betaβ-linkage
  4. D
    amylose is made up of glucose and galactose
View written solutionFree

Correct answer: A

Amylose and amylopectin are polymers of α\alpha α-D-glucose, so β\beta β-link is not possible. Amylose is linear with 1 →\to→ 4 α\alpha α-linkage whereas amylopectin is branched and has both 1 →\to→ 4 and 1 →\to→ 6 α\alpha α-linkages.
