D-Glucose-L-cysteine Maillard system

Scheme 1. Nonspecific initial phase in the D-glucose/L-cysteine Maillard system (b = keto/enol tautomerism, c = allylic dehydration, d= allylic deamination)...

The identification of unlabled pyruvate and 2-mercaptopropionic acid in [ C]-D-glucose/L-cysteine Maillard systems clearly indicates a degradation pathway via 6-elimination. In the corresponding [l-i Cj-D-glucose/L-methionine model experiment,...
