Question

One which does not stabilize secondary and tertiary protein?

• A. H-H linkage
• B. S-S linkage
• C. Vanderwoal’s force
• D. Hydrogen bonding

Answer 1

Answer: (A)

H-H linkage

Answer 2

Among the given options, H-H linkage does not stabilize the secondary and tertiary structure of proteins. This is because H-H linkage refers to a hypothetical interaction between two hydrogen atoms, and such an interaction is not known to play a significant role in stabilizing protein structures.
On the other hand, hydrogen bonding, S-S linkage, and van der Waals forces all contribute to stabilizing the secondary and tertiary structure of proteins. Hydrogen bonding helps to stabilize the structure of protein helices and sheets, while S-S linkages are important for stabilizing the three-dimensional structure of many proteins. Van der Waals forces are weak, non-specific forces that contribute to the overall stability of protein structures, particularly in hydrophobic regions of the protein.
