M. Declercq et D. Rolin, INFLUENCE OF THE GELATIN OXIDATION-STATE ON THE AG+ GELATIN INTERACTION AT PH 5, Imaging science journal, 45(3-4), 1997, pp. 107-109
The role of histidine becomes important at pH 5. Ability to form His(2
)Ag(+) complexes decreases with the gelatin oxidation. A relation is f
ound between the content of the gelatin histidine residues involved in
the Ag+ binding and the gelatin methionine content.
