Question

Difference between globular proteins and fibrous proteins.

Answer 1

Hint:First we should be aware of the term globular and the fibrous proteins. Then we have to compare them on various aspects and bases. Some of these are essential like the physical appearance and the type of shapes. Apart from them we have to give their examples like the haemoglobin for the globular and the keratin for the fibrous. Then we also have to give the difference in their functionality in order to conclude the answer.

Complete answer:
We just have to give the different points for each of the type:
Globular proteins
-Globular proteins are pretty highly branched or termed as coiled structures
-Globular proteins are highly made up of not just primary, secondary but also the tertiary and in many cases occasionally quaternary structures.
-Haemoglobin is an well explained example of globular protein
-Globular proteins have many multiple functions as they are widely used to form enzymes, cellular messengers, amino acids.
Fibrous proteins
-Fibrous proteins are pretty elongated strand-like structures and they are usually present in the form of either rods or wires.
-Fibrous proteins have their basic structure made up of primary and secondary structures.
-Examples of Fibrous proteins are keratin, collagen and elastin.
-Fibrous proteins just act only as structural proteins.

Note:Both the proteins mainly differ on the aspect of the physical nature and the appearance. They both perform many important tasks similarly and show almost all the characteristic reactions commonly to each other.
