A paper entitled "The Detection of Ethylketen and enol-Crotonaldehyde in the Vapour-phase Photolysis of trans-Crotonaldehyde" reported some of my work in 1968 after I had moved on to graduate school.
We could show spectroscopically that the enol-aldehyde of methylglyoxal was really the enzyme's product49.
The formation of an enol may explain the anti-microbial properties since enols are known to show disinfectant properties.
Including plastic ingredients like phthalates and bisphenol-A, these commonplace compounds are known to mimic female hormones and thwart the production of testosterone, explains Shanna Swan, Ph. D., director of the Center for Reproductive Epidemiology at the University of Rochester School of Medicine and Dentistry.
Chemical shift equivalence by rapid interconversion of structures may occur due to rapid rotation about bonds or due the rapid chemical changes such as keto-enol tautomerism.
Although acetone has two possible forms, the keto - and the enol-forms
)  P (S) - 2-hydroxy-1-indanone + NAD+ (, 95% S-enantiomer, product is formed by incorporation of a single atom of molecular oxygen rather than by dioxygenation of enol tautomers of the ketone substrate )  S 2-iodoindane + O2 + NADH
