Which of the following types of bonds or interactions is primarily involved in stabilizing the alpha-helix and beta-sheet structures of proteins?Question 4Answera.Hydrophobic interactionsb.Hydrogen bondsc.Peptide bonds d.Ionic bonds
Solution
The primary type of bond involved in stabilizing the alpha-helix and beta-sheet structures of proteins is the hydrogen bond (option b).
Here's a step-by-step explanation:
-
Proteins are made up of amino acids, which are linked together by peptide bonds (option c). However, these bonds are not primarily responsible for the specific structures of alpha-helices and beta-sheets.
-
Alpha-helices and beta-sheets are secondary structures of proteins. These structures are primarily stabilized by hydrogen bonds (option b).
-
In an alpha-helix, the hydrogen bonds are formed between the oxygen atom of the carbonyl group in one amino acid and the hydrogen atom of the amino group in another amino acid, which is typically the fourth amino acid away in the sequence.
