ketoses

Now the only thing necessary for my strange result to make sense was to find an isotope effect in the color reaction for ketoses in acid.

Fructose-6-P formation from glucose-6-P in H2O and D2O, as measured colorimetrically by the Roe test for ketoses.

Such transitions would be more easily explained on the assumption that the celluloses are composed in part of polyanhydrides of the ketoses.

In this important point the celluloses behave as ketoses.

In the systematic investigation of the nitric esters of the carbohydrates (p. 41) Will and Lenze have definitely differentiated the ketoses from the aldoses, as showing an internal condensation accompanying the ester reaction.

They also lay stress upon the superior stability of the nitrates of the anhydrides, especially of the ketoses.

2S-aldoses produce ketoses that exchange their 1S proton11.

C_ {6} H_ {12} O_ {6} - 4H_ {2} O + HBr = C_ {5} H_ {3} (CH_ {2} Br) O and generally the ketoses are distinguished from the aldoses by their susceptibility to condensation.

(p. 38) The authors have studied the nitric esters of a typical series of the now well-defined carbohydrates -- pentoses, hexoses, both aldoses and ketoses -- bioses and trioses, the nitrates being prepared under conditions designed to produce the highest degree of esterification.

If you do that, you will lose fine whether you’re always in ketoses or not.
