Class 11 Biology - Chapter Biomolecules NCERT Solutions | What is meant by tertiary structure of p
Welcome to the NCERT Solutions for Class 11th Biology - Chapter Biomolecules. This page offers a step-by-step solution to the specific question from Exercise 1, Question 3: what is meant by tertiary structure of proteins....
Question 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 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.
