JEE Main 2025 — Biomolecules Question with Solution
From: JEE Main 2025 (Online) 7th April Evening Shift
Question
Given below are two statements :
Statement (I) : On hydrolysis, oligo peptides give rise to fewer number of α-amino acids while proteins give rise to a large number of β-amino acids.
Statement (II) : Natural proteins are denatured by acids which convert the water soluble form of fibrous proteins to their water insoluble form.
In the light of the above statements, choose the most appropriate answer from the options given below :

Show full solutionCorrect option: B
Both Statement I and Statement II are incorrect
Step-by-step explanation
When oligopeptides undergo hydrolysis, they yield a small number of α-amino acids. In contrast, proteins do not produce β-amino acids upon hydrolysis. Thus, Statement I is incorrect.
Furthermore, natural proteins, when subjected to denaturation by acids, do not convert fibrous proteins from a water-soluble to a water-insoluble form, as fibrous proteins are inherently not water-soluble. Therefore, Statement II is also incorrect.
In conclusion, both Statement I and Statement II are incorrect.
