The decongestant effect of ketonic terpenes is well known (c.f. menthone, etc.) and so it is not surprising that these compounds have a calming effect on respiratory conditions.
"All I remember from my class in it, aside from the stinks in the lab, is that the human sex hormones are much the same, except that the female is ketonic and the male is alcoholic."
The anti-microbial properties, however, are rather more difficult to explain on the basis of ketonic structures.
O although by a little further 'manipulation' of the symbols the change could, of course, be represented by reference to the ketonic formula.
The transition from a cellulose-ketone to the lignone-ketone involves a simple condensation without rearrangement; from which we may argue back to the greater probability of the ketonic structure of the cellulose.
This latter method is being extended to the investigation of typical celluloses, and the results appear to confirm the view that cellulose may be of ketonic constitution.
Simultaneously there is formed an oxygluconic acid, which appears to be a ketonic acid of formula
The phenol process is therefore equally accurate, has the advantages above noted, and, in addition, is less liable to error from the pressure in the distillates obtained from vegetable substances of volatile products, e.g. ketonic compounds, accompanying the furfural.
We revert with preference to a definitely ketonic formula, for which, moreover, some farther grounds remain to be mentioned.
As the reaction is mainly confined to the cellulose of the fibre, we have this additional evidence that the typical carbonyl is of ketonic function.
