Question 3
What is meant by tertiary structure of proteins?


Answer:

Answer

The helical polypeptide chain undergoes coiling and folding to form a complex three-dimensional shape referred to as tertiary structure of proteins. These coiling and folding hide the non-polar amino acid chains in the interior of molecule and expose the polar side chains to the exterior. The tertiary structure is held together by the weak non-covalent interacting formed between various parts of the polypeptide chain.
