Question

What is a difference between starch and glycogen?

Answer 1

Glycogen Also known as animal starch is a source of energy that can be found in animals only.Glycogen consist of a single molecule and it's structure is branched purely. The animal liver and muscles are responsible in the creation of glycogen. The glycogen act as an emergency reserves when a human body suddenly need a an ample amount of energy STARCH Starch on the other hand can solely be found in green plants and staple food such as oats, barley and potatoes. Glycogen has a single molecule while starch has double molecules. In term of structure glycogen are branched out purely while starch consist of branch and chain component

Answer 2

Answer:

For both animals and fungi, glycogen serves as both a vital energy source and a form of storage.

A crucial part of how plants store energy is starch.

Explanation:

1.Glycogen: -

For both animals and fungi, glycogen serves as both a vital energy source and a form of storage. Alpha-glucose serves as the monomer unit in the production of glycogen. It is located in the cytoplasm of the cell as tiny granules. Glycogen is kept in reserve in human beings in the muscle and liver cells.

2. Starch: -

A crucial part of how plants store energy is starch. The glucose that plants produce is transformed into insoluble storage materials like starch and lipids. The primary dietary component in many plants and fruits, including amyloplasts, is starch.

Basic differences between the two are as below: -

1. Definition: The primary substance in both animals and fungi, glycogen is a polymeric form of glucose called glycogen.

  The primary storage carbohydrate for plants is starch, a complex molecule of glucose.

2. Chains of monomers: The monomer units that make up glycogen form the short, branching chains. Alpha glucose, one of its monomer units, is kept together by glycosidic linkages.

The two additional polymers that make up starch are called amylose and amylopectin; the former forms coiled and linear chains, whereas the latter forms branching chains.

3. The chemical formula of glycogen is C₂₄H₄₂O₂₁

  Starch has the chemical formula (C₆H₁₀O₅)n.

4. Appears in the form of: - Glycogen exists as tiny granules.

    Grain forms of starch are present.

5. Function : - Glycogen functions as the animal's energy-storing carbohydrate. Starch functions as the plant's energy-storing carbohydrate.
