ResumoMaillard reaction of bovine serum albumin with glucose. Determination of 2- formyl-5-(hydroxymethyl)pyrrole-1-norleucine by high-performance liquid chromatography after alkaline hydrolysis Reactions between glucose and bovine serum albumin proceed predominantly at the side chain amino groups of lysine residues. Among other products, proteinbound 2-formyl-5-(hydroxymethyl)pyrrole-1-norleucine is formed. After alkaline hydrolysis and fractionation of the protein hydrolysate on RP-18 material this substance can be separated by high-performance liquid chromatography. The identity of the norcleucine derivative with a synthesized compound can be determined with fast atom bombardment-mass spectrometry spectral data. A colour reaction with thiobarbituric acid is also suitable for detection.
