(a)
To determine: The structure of the phenylthiohydantoin derivative of alanine.
Interpretation: The structure of the phenylthiohydantoin derivative of alanine is to be determined.
Concept introduction: The process in which a proper series of amino acids is maintained in the peptide chain is known as edmann degradation. this process includes the labelling of terminal amino residue followed by the cleavage of this terminal amino residue from the peptide chain. the peptide bonds between other amino acids do not get disturb during this process.
(b)
To determine: The structure of the phenylthiohydantoin derivative of tryptophan.
Interpretation: The structure of the phenylthiohydantoin derivative of tryptophan is to be determined.
Concept introduction: The process in which a proper series of amino acids is maintained in the peptide chain is known as edmann degradation. this process includes the labelling of terminal amino residue followed by the cleavage of this terminal amino residue from the peptide chain. the peptide bonds between other amino acids do not get disturb during this process.
(c)
To determine: The structure of the phenylthiohydantoin derivative of lysine.
Interpretation: The structure of the phenylthiohydantoin derivative of lysine is to be determined.

(d)
To determine: The structure of the phenylthiohydantoin derivative of proline.
Interpretation: The structure of the phenylthiohydantoin derivative of proline is to be determined.
Concept introduction: The process in which a proper series of amino acids is maintained in the peptide chain is known as edmann degradation. this process includes the labelling of terminal amino residue followed by the cleavage of this terminal amino residue from the peptide chain. the peptide bonds between other amino acids do not get disturb during this process.
