PHOTOINTERACTION OF BENZOPHENONE TRIPLET WITH LYSOZYME [PDF]

open access: yesPhotochemistry and Photobiology, 1989
AbstractThe quenching of the benzophenone triplet by lysozyme and its constituent amino acids in aqueous solutions have been studied. Native lysozyme quenches the benzophenone triplet with a high rate constant, 4 × 109M‐1s‐1. The quenching process takes place with production of significant amounts of free ketyl radicals, φketyl=0.56, but with a very ...

Safety of benzophenone to be used as flavouring [PDF]

open access: yesEFSA Journal, 2017
Benzophenone [FL-no: 07.032] has been evaluated as a flavouring substance, in FGE.69, by the EFSA Panel on Food Additives, Flavourings, Processing Aids and Materials in Contact with Food in 2008. Benzophenone was evaluated also by JECFA (2011) and by IARC (2013) based on studies that were not considered in the EFSA opinion on FGE.69.

CHARACTERIZATION AND ANTIPARASITIC ACTIVITY OF BENZOPHENONE THIOSEMICARBAZONES ON Trypanosoma brucei brucei [PDF]

open access: yesScientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2011
The structure of four synthesized thiosemicarbazones, substituted or not, of benzophenone has been confirmed by spectrometrical analysis IR, NMR 1H and 13C. Their anti-trypanosomal activities were evaluated on Trypanosoma brucei brucei.
