Question

Which structural level of a protein would be least affected by a disruption in hydrogen bonding?
a. primary structure
b. secondary structure
c. tertiary structure
d. quaternary structure

Accepted Answer

Hello everyone and welcome to today's video and today we're going to be talking about protein structure. So which of the following bonds do you expect in a protein secondary structure? Remember that in a secondary structure of a protein. We have certain inter molecular interactions that occur between the amino assets that make up the protein and some of these are the alpha hill assis and the beta pleaded sheets. And these are going to make up this secondary structure of the protein. Now what makes up these alpha analysis and these better fitted sheets where they're going to be made up by certain inter molecular interaction. Now let's go over answer choices so that we may begin solving these problems. Beginning by answer choice, a ionic bonds. These are present in between ions and these are inter molecular interactions. So we're going to cancel them out because here we're talking about proteins. Then we have answer choice the metallic bond again, this is between metals. This is not going to be present in proteins. So we're also going to cancel it out. Now we have di sulfide bonds and we have hydrogen bonds. These two are actually going to be present in proteins. However, these di sulfide bonds are covalin bonds and they form in the protein's tertiary structure. They help maintain this three D shape that forms there. Since we're talking about the secondary structure in our protein, we're going to cancel them out and this all leaves us with hydrogen bond. These hydrogen bonds are going to be the inter molecular interactions that create these foothill Asus and this beta pleated sheets between and use makeup this secondary structure of this protein. So answer choice C hydrogen bonding is going to be the final answer to this question. I really hope this video helped you, and I hope to see you on the next one.
