Protein primary structure determination is a biochemical methodology defined by the sequential elucidation of amino acid sequences following complete hydrolysis into constituent residues and subsequent separation via chromatographic techniques based on differential solubility. The core theoretical framework relies on specific enzymatic or chemical cleavage rules that fragment polypeptides at distinct bond sites to establish sequence overlaps, while Edman degradation employs N-terminal selective labeling for iterative sequential analysis without disrupting the peptide backbone integrity. This process fundamentally translates genetic information stored in nucleotide sequences into linear amino acid arrangements within proteins, serving as a critical mechanism for characterizing molecular identity and validating the central dogma of biology regarding genotype-phenotype expression.
