Explain the tertiary and quaternary structure of protein with example.

1.	Explain the tertiary and quaternary structure of protein with example.
Answer» Tertiary structure: 1. In tertiary structure the peptide chains are much looped, twisted and folded back on themselves due to formation of disulphide bonds. 2. Such loops and bends give the protein a tertiary structure. 3. E.g. Myoglobin, enzymes.. Quaternary structure: 1. When a protein has more than two polypeptide subunits their arrangement in space is called quaternary structure. 2. E.g. Haemoglobin.

Answer»

Tertiary structure:

1. In tertiary structure the peptide chains are much looped, twisted and folded back on themselves due to formation of disulphide bonds.

2. Such loops and bends give the protein a tertiary structure.

3. E.g. Myoglobin, enzymes..

Quaternary structure:

1. When a protein has more than two polypeptide subunits their arrangement in space is called quaternary structure.

2. E.g. Haemoglobin.
