“…Forming localized links is due to the polarity of sulfides and carboxylic amino, of functional groups of proteins [28]. This photo-structuring is due to macromolecular cross-linking of denatured proteins [29]. The recombination involves macroradical species formation by the transfer of electrons from the electron-donating functional groups of the denatured protein molecules to excited-state chromium species (VI) [28] [30] and implies that the photochemical reactions obscure the matrix and the reduction of Cr (VI) and oxidation of proteins simultaneously; it was generating the modification of the supramolecular structure of biopolymers [31].…”

Holographic recording analysis was performed on the films that were sensitized with ammonium dichromate with albumin of hen and quail (Gallus gallus and Callipepla cali) as abiopolymeric photosensitive matrix. The samples were exposed to an He-Cd laser, λ = 442 nm, at various concentrations, and diffraction efficiencies were measured as a function to the energy, thickness, protein density, aging time, and spatial frequencies. The photosensitivity was measured as a function of storage time, and the gratings were recorded in real time. The photochemical processes involved in the formation of holographic image are described. The results indicate the behavior of colloidal systems based on albumin bird build holographic recording materials.

The Dichromated Gelatin (DCG) known as medium for the phase holograms registration and production of special planographic printing plates as well as the solutions of dichromates in alcohols have been studied for chromium compound reactions and phase-conformational transformations of denatured collagen molecules in their own polymer matrix. One-and multielectron transfer schemes are discussed as well as the delocalization of an electron along the rnacromolecular chains and polypeptide fragments and phase conformational changes in them.
