Detailed explanation-1: -Glucosazone (from glucose, fructose or mannose) forms broomstick or needle-shaped crystals.
Detailed explanation-2: -Osazones are characteristic crystals resulting from the reaction of reducing sugars with phenylhydrazine. When detected, these osazones can be correlated with their associated disorders such as arabinose in autism & alzheimer’s disease and galactose in Galactosemia.
Detailed explanation-3: -Glucose, fructose, galactose and mannose formed needle shape osazone.
Detailed explanation-4: -Osazone test is a chemical test used to detect reducing sugars. This test even allows the differentiation of different reducing sugars on the basis of the time of appearance of the complex. This test is also termed Phenyl hydrazine test based on the reagent used for this test.
