Osazone formation was developed by Emil Fischer, [3] who used the reaction as a test to identify monosaccharides. The formation of a pair of hydrazone functionalities involves both oxidation and condensation reactions. [4] Since the reaction requires a free carbonyl group, only "reducing sugars" participate.
Items from Louisville Stoneware are in the Smithsonian Institution and White House. [3] In addition, Queen Elizabeth II was presented a music box made by Louisville Stoneware, given by the wife of Kentucky's governor Ernie Fletcher , that played My Old Kentucky Home when the Queen visited Churchill Downs for the Kentucky Derby in 2007.

Photographs of the actual demolition by explosion of a defunct Belknap building were used as promotional preview advertising for the 1993 film, Demolition Man. [citation needed] The Heyburn Building, on the National Historic Register since 1979, until 1955 was the tallest building in Kentucky. It was completed in 1928 and named for William R ...
In order to track Recovery Kentucky outcomes, the state contracts with the University of Kentucky to conduct an annual survey. In its 2014 report, researchers claimed that 92 percent of all illicit-drug addicts who went through Recovery Kentucky were still drug-free six months after discharge.

Melzer's reagent can be used to test whether spores are amyloid, nonamyloid, or dextrinoid. Spores that stain bluish-gray to bluish-black are amyloid; Spores that stain brown to reddish-brown are dextrinoid; This test is normally performed on white spored mushrooms. If the spores are not light colored, a change will not be readily apparent.
The mechanism of carbonyl oxidation by iodine(III) reagents varies as a function of substrate structure and reaction conditions, but some generalizations are possible. Under basic conditions, the active iodinating species are iodine(III) compounds in which any relatively acidic ligands on iodine (such as acetate) have been replaced by alkoxide. [1]
