Question

What are the two types of secondary structures found in polypeptides, and what maintains them? What stabilizes the tertiary structure of a polypeptide?

Accepted Answer

Hello everyone here We have a question asking us to identify the incorrect statement about protein structure. A The primary structure of proteins is the sequence of amino acids that form their chains. This is correct. Be the alpha helix is an example of a protein secondary structure. This is correct. See the tertiary structure of a protein is formed by further folding of the protein secondary structure. This is correct. See the sub units of a co ordinary structure are held together by ionic bonds. This is incorrect. They are held together by hydrogen bonds and van der Waals forces between non polar side chains. So our answer is, the the sub units of a co ordinary structure are held together by ionic bonds. Thank you for watching. Bye!
