Predict what would happen to the secondary structure of a protein if an alcohol that disrupts hydrogen bonding were added.

Choose one or more answer (if applied):
A. Nothing would happen to the protein; hydrogen bonding is not important for secondary structure

B. The beta sheets would unfold, disrupting protein structure

C. The a helixes would unfold, disrupting protein structure

D. Individual amino acids would be hydrolyzed from the protein, disrupting protein structure

Answer #1

C- The helix would unfold disrupting the protein structure.

B- Beta sheet would unfold disrupting the protein structure.

The alcohol denatures the proteins secondary structure it breaks the hydrogen bond present between amide groups of secondary structure. The alcohol denatures intra molecular hydrogen bonding between side chain. The hydrogen bonds hold together the helix and beta sheets. Denaturing hydrogen bonds with alcohol would cause disruption of helix and beta sheets followed by denaturation of protein molecule.

     Distinguish between the different levels of protein structure, including primary, secondary, tertiary, and quaternary Question Is the following statement true? If not, explain why not: Since the secondary structure of a protein results from hydrogen bonding between components shared by all amino acids (a hydrogen on an amide N on one amino acid interacts with an oxygen on the carbonyl of another amino acid), the secondary structure does not depend on the specific amino acid groups (the R-groups) in the amino acid chain. Select...

    QUESTION 2 Select the CORRECT statements (chose all that are correct). Secondary protein structures are held together by disulphide bridges/bonds. Alpha helices and beta sheets are common secondary protein structures. Tertiary protein structures are held together by covalent bonds only. Secondary protein structures are held together by hydrogen bonds only. All proteins have a quaternary protein structure. Amino acids linked with a peptide bond make up the primary protein structure.
