JEE Advanced levelSingle correct optionDifficulty 3 of 3bm103

The tetrapeptide Ala-Gly-Ser-Val (N-terminal to C-terminal) is partially hydrolysed. Counting every distinct free amino acid, dipeptide and tripeptide that can arise from cleavage of its peptide bonds (the original tetrapeptide is not counted), the number of distinct products possible is

  1. A7
  2. B10
  3. C9
  4. D6

Answer: C

Fragments are contiguous stretches of the chain: single residues , dipeptides (Ala-Gly, Gly-Ser, Ser-Val) and tripeptides (Ala-Gly-Ser, Gly-Ser-Val). Total = .
