What happens when a primary structure forms a secondary structure?

Question

Accepted Answer

Hello everyone. Today we have the following problem which of the following statements about protein, primary and secondary structures are correct. So the first statement says the primary structure for protein refers to the linear sequence of amino acids in the polypeptide chain. And this is correct. Moreover, the primary structure is held together by peptide bonds. Statement two says a secondary structure of a protein is stabilized by hydrogen bonds between side chains of amino acids and that this is actually going to be false. So the hydrogen bonds are present but they are between the backbone, am I hydrogen atom and the carbonell oxygen atoms. So we know that the second statement can't be involved in our answer. So we can eliminate Antos ac and D leaving us with rays B as the correct one. But let's see why. Statement three is correct. So it says that the alpha helix and beta sheet are types of secondary structures and proteins. And this is correct and these state structures are stabilized by hydrogen bonding patterns in the backbone. And then the fourth statement is incorrect. It says that secondary structures such as alpha helices and beta streets are formed through interactions between the R groups of amino acids. And we know that this is not correct as they are formed through hydrogen bonding of the polypeptide backbone. And with that, we have solved the problem overall, I hope this helped. And until next time.
