Medium MCQ +4 / -1 PYQ · JEE Mains 2025

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 :

  1. A <p><b>Statement I</b> is incorrect but <b>Statement II</b> is correct</p>
  2. B <p>Both <b>Statement I</b> and <b>Statement II</b> are incorrect</p> Correct answer
  3. C <p>Both <b>Statement I</b> and <b>Statement II</b> are correct</p>
  4. D <p><b>Statement I</b> is correct but <b>Statement II</b> is incorrect</p>

Solution

<p>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.</p> <p>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.</p> <p>In conclusion, both Statement I and Statement II are incorrect.</p>
