A tripeptide (X) on hydrolysis gives three amino acids (A)(NH_(2)-unde

1.	A tripeptide (X) on hydrolysis gives three amino acids (A)(NH_(2)-underset(R )underset(\|)(C )H-COOH), (B)(NH_(2)-underset(R ')underset(\|)(C )H-COOH), and (C )(NH_(2)-underset(R ')underset(\|)(C )H-COOH).(X) and reaction with NH_(2)NH_(2) gives a dipeptide (Y) and amino acid (B). The dipeptide (Y) is hydrolysed by carboxypeptidase enzyme and gives amino acid (A). what is the structure of (X)?
Answer» SOLUTION : FORM the above reaciton, it is clear that the AMINO acid (C ) is `N`-terminal. HENCE the squence is `(CrarrArarrB)`.
