What is the difference between fibrous and globular proteins?
Homework Answers
Difference between fibrous and globular proteins :
1.shape and solubility
Globular protein is spherical and formed colloids with water and also dissolved in water. These are soluble in water, acids, and base. These are called as spheroproteins.
Example- Hemoglobin
Fibrous proteins are elongated strand-like structures and form the structure of rods or wires. These are also called as scleroproteins.
These are insoluble in water, weak acids and weak bases but soluble in strong acids and alkalis
Example-keratin, collagen, and elastin
2.Functions
Globular proteins form enzymes, cellular messengers, amino acids, hormones and also helps in transportation of vital nutrients like oxygen through hemoglobin.
Fibrous proteins form connective tissue, tendons, and fibers of the muscle and also helps in the movements of the muscles and tendons at a joint. Fibrous protein like Fibroin,used to produce silk by silkworms and webs of spiders.

Hemoglobin consists of four globular proteins, each formed from a polypeptide chain. Each globular protein contains a nonprotein group with an iron ion. This iron ion binds to an oxygen molecule. Thus, every hemoglobin protein can bind four oxygen molecules. Select the correct statement about oxygen transport below. a. Myoglobin transports oxygen through the bloodstream to tissue. b. To carry oxygen, iron must be in its nonheme form. c. Erythrocytes contain abundant myoglobin for transporting oxygen. d. Hemoglobin is found...
