Question:
One which does not stabilize secondary and tertiary protein?
One which does not stabilize secondary and tertiary protein?
Updated On: Sep 30, 2024
H-H linkage
S-S linkage
- Vanderwoal’s force
- Hydrogen bonding
Hide Solution
Verified By Collegedunia
The Correct Option is A
Approach Solution - 1
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.

Concepts Used:
Biomolecules
Biomolecules are the most essential organic molecules, which are involved in the maintenance and metabolic processes of living organisms. These non-living molecules are the actual foot-soldiers of the battle of sustenance of life.
There are four major classes of Biomolecules – Carbohydrates, Proteins, Nucleic acids and Lipids.
- Carbohydrates are chemically defined as polyhydroxy aldehydes or ketones or compounds which produce them on hydrolysis.
- Proteins are another class of indispensable biomolecules, which make up around 50per cent of the cellular dry weight. Proteins are polymers of amino acids arranged in the form of polypeptide chains. The structure of proteins is classified as primary, secondary, tertiary and quaternary in some cases.
- Nucleic acids refer to the genetic material found in the cell that carries all the hereditary information from parents to progeny. There are two types of nucleic acids namely, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The main function of nucleic acid is the transfer of genetic information and synthesis of proteins by processes known as translation and transcription.
- Lipids are organic substances that are insoluble in water, soluble in organic solvents, are related to fatty acids and are utilized by the living cell.
