WebPhosphonopeptides are mimetics of peptides in which phosphonic acid or related (phosphinic, phosphonous etc.) group replaces either carboxylic acid group present at C-terminus, is located in the peptidyl side chain, or phosphonamidate or phosphinic acid mimics peptide bond. WebBoth react efficiently with primary amine groups (-NH2) in pH 7–9 buffers to form stable amide bonds. The phosphonic acid or phosphonate ester groups can then be used to enrich crosslinked peptides using immobilized metal affinity chromatography (IMAC) or metal oxide affinity chromatography (MOAC).
