Q.3:- What is meant by tertiary structure of proteins?

 

Answer

The helical polypeptide chain undergoes coiling and folding to form a complex three-dimensional shape is called tertiary structure of proteins. These coils and folds are arranged to hide the non-polar amino acid chains and to expose the polar side chains. The tertiary structure is held together by the weak bonds formed between various parts of the polypeptide chain.
