Which of the following polymer is stored in the liver of animals?

CONCEPT:

Storage Polymers in Animals

• Animals store energy primarily in the form of glycogen, a highly branched polysaccharide.
• Glycogen is mainly stored in the liver and muscle tissues to provide a quick source of glucose when energy is needed.
• It is structurally similar to amylopectin but is more extensively branched, allowing rapid mobilization of glucose units.

EXPLANATION

• Mylopectin (option 1) is a plant starch polymer, serving as a storage polysaccharide in plants, not animals.
• Glycogen (option 2) is the main animal storage polymer found in the liver and muscles.
• Mylose (option 3) refers to amylose, a linear plant starch component, not stored in animals.
• Cellulose (option 4) is a structural polysaccharide in plants and not used for energy storage in animals.
• Therefore, glycogen is the polymer stored in the liver of animals.

Hence, the correct answer is Glycogen.
