Sorry, no etymologies found.
The chemical composition of both ovoflavin and lactoflavin proved to be virtually identical.
"The beautiful yellow pigments" turned out to be riboflavin, although Kuhn called it both lactoflavin and ovoflavin because they had first abstracted it from milk and egg whites.
Fortunately, they soon discovered a breakdown product of lactoflavin, called lumiflavin, which they were able to crystallize.
Determining if the flavins were precursors or the vitamin itself was initially elusive due to difficulties crystallizing the lactoflavin, which hindered the structural analysis.
Finally they had proof that lactoflavin was vitamin
And after determining the structure of lumiflavin, they were able to extrapolate enough information to synthesize lactoflavin and thereby determine its composition.
His important contributions to the chemistry of the flavins led to identification of lactoflavin as part of the complex originally thought to be vitamin B2.
The lactoflavin, for instance, combines, with the aid of phosphoric acid, with an albuminous substance, and only in this way the yellow respiratory ferment is formed.
