(a)
Interpretation:
In Bacitracin A, the amino acid residues and the configuration of the same along with non-amino acid residue need to be identified.
Concept introduction:
The amino acid residue is in a given compound is identified by finding the peptide bond. Then assigning the side chain for the corresponding amino acid residue. If the configuration of the amino acid residue is “L-amino acid” means it is naturally occurring and if it is a “D-amino acid” it is enantiomer of “L-amino acid”
To identify: the amino acid residue in Bacitracin A that are naturally occurring.
(b)
Interpretation:
In Bacitracin A, the amino acid residues and the configuration of the same along with non-amino acid residue need to be identified.
Concept introduction:

If the configuration of the amino acid residue is “L-amino acid” means it is naturally occurring and if it is a “D-amino acid” it is enantiomer of “L-amino acid”
To identify: the amino acid residue in Bacitracin A that are D-amino acids.
(c)
Interpretation:
In Bacitracin A, the amino acid residues and the configuration of the same along with non-amino acid residue need to be identified.
Concept introduction:
The amino acid residue is in a given compound is identified by finding the peptide bond. Then assigning the side chain for the corresponding amino acid residue. If the configuration of the amino acid residue is “L-amino acid” means it is naturally occurring and if it is a “D-amino acid” it is enantiomer of “L-amino acid”
To identify: the amino acid residue in Bacitracin A that are not naturally occurring and its enantiomer also.
