Macrokinetic Regularities of Chemiluminescence Development in the Course
of Non-Enzymatic Glycation in Aqueous Solutions of Glycine and D-Glucose
(Maillard Reaction)
Abstract
Maillard
reaction in water solutions of б-amino acids (glycine, L-lysine, L-arginine)
and reducing sugars (glucose, xylose) has been studied. Among the observed
macrokinetic regularities of CL development in aqueous solutions of glycine and
glucose at the room temperature there were growth and decay of the CL
"slow flash", latent period, "stationary luminescence" and
appearance of CL "quick flash" after oxygen access termination or
after ions Fe(II) addition. Correlation between kinetics of the CL "slow
flash" development and concentration of the main participants has been
shown. For the first time the phenomenon of initiated CL "slow flash"
that appeares in the solutions at the room temperature after brief heating up
to 94oC has been revealed and it has been shown that the process
continued at physiological pH values.
