Which of the given statement is not true for glucose?
Glucose exists in two crystalline forms alpha and beta
Explanation for the correct option:
Glucose functions
Glucose's chemical equation ( ). It's found in fruits and honey, and it's the most prevalent reason for large blood sugar in higher animals. Its metabolism must be carefully monitored because it is a major source of energy for overall cell activity.
Correct answer
Option(d) The fact that glucose occurs in two crystalline forms, alpha, and beta, is not true.
Explanation for the incorrect options:
Option(a)
Due to the obvious sheer aldehydic group, oxime is developed when D-glucose combines with hydroxylamine. D-glucose pentaacetate does not react with hydroxylamine since such aldehyde analysis was performed.
Option(b)
While glucose and hydroxylamine are used to manufacture oxime, cyanohydrin is generated without any need for hydrogen cyanide. In its open-chain structure, glucose has a carbonyl group.
Option(c)
Glucose seems to have an aldehyde group in its open structure, however, it also forms a cyclic acetal structure (also called pyranose). Despite the reality that it is a weak base, this system is focused and stable, and Schiff's reagent has no effect on it. It also fails Schiff's test since it does not release hydrazone.
Therefore, Option(d) There still are two crystalline forms of glucose: alpha and beta.
