Chapter 21, Problem 4A

Interpretation Introduction

Interpretation:

Use of Fibrous and globular proteins, and their general shape needs to be explained.

Concept introduction:

Protein- The primary structure of a protein is fixed as soon as the amino acids are linked together.

There are two main classes of the proteins, fibrous and globular.

Answer to Problem 4A

Fibrous proteins are used for the formation of different types of extra structural material for the human body.

Globular is used in the biological reaction of the body.

The basic structural strand arrangements are different in both types of proteins.

Explanation of Solution

Fibrous protein- Fibrous proteins play an important role in structure-function and manufacturing the keratin, elastin, actin types of fiber for the human body.

Globular protein- The catalytic activity and regulatory function are completed with the help of globular proteins.

General shapes of two different proteins are-

Fibrous protein- These types of proteins are composed of long and thin strands.

Globular protein- The more compact coiled and round shape is the basic structure of these types of proteins.

Fibrous protein Globular protein

Conclusion

Proteins are the complex substance that covers the huge portion of the living organism

The main portion of the human body is consists of proteins such as muscle, bone, organs, skin, nails. So it is known as the building block for the human body. The biochemical reactions are completed with the help of enzymes.

Different types of a strand of and their arrangements formed two different shapes of proteins, fibrous and globular.
