Explain types of proteins based on molecular shape.
Answers
Answer:
On the basis of molecular shape, proteins are classified into two types—fibrous proteins and globular proteins. ... They are folded to form a spherical shape, have intramolecular hydrogen bonding and have weak intermolecular forces as compared to fibrous proteins
Answer:
1. Fibrous Proteins:
When the polypeptide chains run parallel and are held together by hydrogen and disulfide bonds, then the fiber-like structure is formed. Such proteins are generally insoluble in water. These are water-insoluble proteins.
Example – keratin (present in hair, wool, and silk) and myosin (present in muscles), etc.
2. Globular Proteins:
This structure results when the chains of polypeptides coil around to give a spherical shape. These are usually soluble in water.
Example – Insulin and albumins are common examples of globular proteins.
