The following are the sugars that formed needle shaped or broomstick crystals during Osazone test, EXCEPT:
|
|
Galactose
|
|
|
Xylose
|
|
|
Glucose
|
|
|
Fructose

Explanation:
Detailed explanation-1: -Glucosazone (from glucose, fructose or mannose) forms broomstick or needle-shaped crystals.
Detailed explanation-2: -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.
Detailed explanation-3: -So, Galactose forms osazones different from the other three.
