Question

Determine whether each of the following statements describes the primary, secondary, tertiary, or quaternary structure of a protein.

d. Amino acids react in a condensation reaction to form a peptide bond.

Accepted Answer

All right. Hello everyone. So this question is asking us to determine the level of protein structure described by the statement below whether it's primary secondary tertiary or quaternary. And the statement says that during protein synthesis, the amino group of leucine reacts with the carboxyl group of isoleucine to form a peptide bond creating a specific sequence within the polypeptide chain. So first, let's start with a very quick summary of the different levels of protein structure starting off with primary structure, which if you recall is simply describing the sequence oops rewrite that again, it's describing the sequence of amino acids that make up the complete polypeptide. And these amino acids are held together by covalent peptide bonds. Now, from here, we move on to secondary structure which is describing local folding. And what I mean by that is that secondary structure is characterized by hydrogen bonding between atoms of the peptide bond backbone. This is in contrast to tertiary structure which describes the ancient molecular forces between amino acid side chains that ultimately produce the complete three dimensional structure of a single polypeptide. And so up to this point, all proteins have up to the tertiary structure And so the ordinary structure is something that you only see in more complex proteins because ordinary structure describes the arrangement of multiple different subunits, multiple different polypeptide chains that will create the functional protein complex once they're combined. So going back to the statement at hand, what piece of information gave away the answer? And that would be two things first peptide bond and then a specific sequence of amino acids because the statement is describing leucine and isoleucine combining together. And so this right here is characteristic of primary folding, right. The statement is describing two amino acids combining via a peptide bond to contribute to the sequence of the polypeptide chain. So it must be primary and there you have it. So with that being said, thank you so very much for watching and I hope you found this helpful.
