Identify fibrous protein from following.
Options:
Answer:
Solution:
Proteins are classified into two types on the basis of their molecular shape: fibrous proteins and globular proteins.
Fibrous proteins have a thread-like structure, where polypeptide chains run parallel and are held together by hydrogen and disulphide bonds. They are generally insoluble in water. Common examples include keratin (present in hair, wool, silk) and myosin (present in muscles).
Globular proteins have a spherical shape formed by the folding of polypeptide chains. They are usually soluble in water. Examples include insulin, albumins (such as serum albumin), and legumelin.
Therefore, myosin is a fibrous protein.
Answer: Myosin
