Why are glucose and fructose in the same osazone?
What does Google know about me?
Thanks for A2A.
Osazones are formed when sugars react with excess phenylhydrazine. This was developed by German scientist Emil Fischer to identify sugars whose stereochemistry differed by just 1 chiral carbon.
Osazones are formed only by reducing sugars. Osazones are highly coloured and crystalline compounds and can be easily detected. Each sugar has a characteristic crystal form of osazones.
Maltose - petal-shaped crystals
Lactose - powder puff-shaped crystals
Galactose - rhombic-plate shaped crystals
Glucose, fructose and mannose - needle-shaped crystals
D-Glucose, D-fructose and D-mannose form the same D-Osazone(as shown in the figure below) because the difference between the C-1 and C-2 between these 3 sugars(Shown in figure above) is masked when osazones crystals are formed.
