Chemistry and biology of nitrosated peptides.


All peptides undergo nitrosation at the terminal primary amino group to generate a diazopeptide and at the peptide N-atoms to produce an N-nitrosopeptide. With acidified nitrite, diazopeptides usually form more readily than N-nitrosopeptides, but quickly decompose. Diazopeptides form rapidly at neutral pH from gaseous nitrogen oxides and are relatively… (More)
