Question

Animal starch is the other name of:

Options
  1. a

    Amylose

  2. b

    Maltose

  3. c

    Glycogen

  4. d

    Amylopectin

Correct Answerc

Glycogen

Detailed Solution

Step 1: Storage Polysaccharides — Glycogen is the primary storage carbohydrate in animals, found mainly in the liver and muscle tissues.

Step 2: Structural Similarity — Like starch (specifically amylopectin), glycogen is a polymer of α-D-glucose\alpha\text{-D-glucose} units, but it is much more branched.

Step 3: Conclusion — Due to its functional and structural similarity to plant starch in animals, it is commonly referred to as "animal starch."

Remember: Glycogen's increased branching leads to faster release of glucose when needed by the body.
