Question
Chapter 5, Problem 41RE
Interpretation Introduction
Interpretation:
The useful information that determines the N-terminal amino acid as a separate step is to be explained.
Concept introduction:
The primary structure of a protein is the linear chain of amino acids bonded to each other with the help of a peptide bond.
Edman degradation is one of the methods used for elucidating the sequence of amino acids present in the peptides of the protein, which is being studied.
