Question

Fibrous protein is
A) Haemoglobin
B) Hordein
C) Globulin
D) Collagen

Answer 1

Hint: It is the most abundant protein in the human body found in the bones, muscles, skin and tendons.

 Complete answer: Fibrous protein is also called Scleroprotein. These types of proteins protect and support the human body. They form connective tissues, tendons, Bone matrices and muscle fibre. Collagen is the substance that holds the body together. Collagen forms a scaffold to provide strength and structure. There are two types of Collagen -: Endogenous collagen is a natural collagen. It is synthesized by the body. Exogenous collagen is synthetic. It comes from an outside source such as supplements. In most collagens, the molecules are packed together to form long, thin fibrils.

Additional information.
>Haemoglobin is not a fibrous protein. It is a protein in the Red blood cells that carry oxygen to the various parts of the body’s organs and tissues and transport CO2 (Carbon Dioxide) from the organs and tissues back to the lungs.
>Hordein is a glycoprotein which is found in Barley and some other cereals.
>Globulin belongs to the family of globular proteins.
> They have high molecular weight and they made in the liver. So, Collagen is the only fibrous protein.

Thus, the correct option is D

Note: Collagen is resorbable. This means that it can be broken down, converted and absorbed back in the body. It can also be formed into compacted solids or lattice-like gels. Collagen for medical use can originate from human, cow, pig or sheep.
Collagens supplements or formulations may help in treating osteoarthritis.
