Answer:
A) identify the N-terminal amino acid of a polypeptide
Explanation:
Edman degradation is a series of chemical reactions that enables the stepwise cleavage of the amino-terminal residue from a peptide/protein. This method sequentially removes N-terminal residues without disrupting peptide bonds between other amino acid residues, thereby obtaining the amino acid sequences from the target peptide/protein. Edman degradation can be defined as a cyclic method in which each residue is cleaved off from the amino-terminal end of the peptide/protein and then identified by reverse-phase chromatography, which is a technique used to separate peptides/proteins on the basis of their hydrophobicity.
