Abstract
1-(5-Amino-5-carboxypentyl)pyridinium chloride (3) and 1-(5-amino-5-carboxypentyl)-3-[1-(5-amino-5-carboxypentyl)-2-piperidyl]pyridinium chloride, anabilysine (4), have been isolated from acid hydrolysates of glutaraldehyde-treated ovalbumin and their structures confirmed by synthesis. It is concluded that the strong chromophore at ca. 265 nm shown by glutaraldehyde-treated proteins is due to the formation of such quaternary pyridinium compounds and that anabilysine residues are important in the cross-linking of proteins by glutaraldehyde.This publication has 6 references indexed in Scilit:
