Question

The difference between amylose and amylopectin is

• A. Amylopectin have $1 \rightarrow 4 \, \alpha $ -linkage and $1 \rightarrow 6 \, \beta $ -linkage
• B. Amylose have $1 \rightarrow 4 \, \alpha $ -linkage and $1 \rightarrow 6 \, \beta $ -linkage
• C. Amylopectin have $1 \rightarrow 4 \, \alpha $ -linkage and $1 \rightarrow 6 \, \alpha $ -linkage
• D. Amylose is made up of glucose and galactose

Answer 1

Answer: (C)

Amylose and amylopectin are polymers of $\alpha $ - D- glucose, so $\beta $ -link is not possible. Amylose is linear with $1 \rightarrow 4 \, \alpha $ -linkage whereas Amylopectin is branched and has both $1 \rightarrow 4$ (for linear chain) and $1 \rightarrow 6 \, \alpha $ -linkages (for branching).
