Kinetics of conversion of dihydroxyacetone to methylglyoxal in New Zealand mānuka honey: Part V - The rate determining step.

Monomer formation from dimeric DHA has previously been suggested as the rate-determining step in formation of methylglyoxal, the bioactive component in mānuka honey. This step was studied by H NMR in DMSO‑d. First order reaction rate was 3.
