JEE Main levelSingle correct optionDifficulty 2 of 3bm094

Complete hydrolysis of one mole of the pentapeptide Ala-Gly-Ala-Gly-Gly gives

  1. A2 mol Ala-Gly and 1 mol glycine
  2. B2 mol alanine and 3 mol glycine
  3. C1 mol alanine and 4 mol glycine
  4. D3 mol alanine and 2 mol glycine

Answer: B

Complete hydrolysis breaks all four peptide bonds (using 4 ) and returns the five free amino acids. Counting the sequence: Ala appears twice and Gly three times.
