Question

α-D- Glucose and β-D- Glucose are not:
A.Epimers
B.Anomers
C.Enantiomers
D.Diastereomers

Answer 1

Hint: The molecular formula of glucose is ${C_6}{H_{12}}{O_6}$ and is the simple sugar. Plants prepare the glucose molecule during the process of photosynthesis using the sunlight, water and carbon dioxide from nature.

Complete step by step answer:
α-D- Glucose and β-D- Glucose are two forms of the glucose which vary because of the position of the OH group in the molecule. The structures of both the forms are shown below.

The chiral carbon is the one which is bounded by four different kinds of groups which are distinct from each other. The Diastereomers which contain more than one chiral carbon but differ in their configuration at one of the chiral carbon are called Epimers. Also they have the same molecular formula but different structural formula.
Diastereomers are also chiral in nature but they are not the mirror images of each other and are non –superimposable on each other whereas Enantiomers are also chiral in nature but they are the mirror images of each other and are non –superimposable on each other. The main difference between these two molecules lies in the mirror images which vary due to structural difference in the placement of the OH group. From mirror images it simply means that by placing the molecules on each other the molecular formula will remain the same but those molecules in which the molecular formula varies are not the mirror images of each other.
Anomers are the cyclic compounds that are Epimers but differ in the configuration at the C1 carbon atom. The C1 carbon atom is also known as chiral or epimeric carbon. If one configuration of the anomers is ketoses then other will be aldoses in nature.
As it is evident from the structure of the α-D- Glucose and β-D- Glucose they both are not enantiomers of each other and are mirror images as well which are non-superimposable on each other.

Note:
In the WHO’s (World Health Organisation) list of most effective medicines needed in a health system Glucose is there and it is the intravenous sugar solution and is recommended in diet for each individual carrying out the necessary metabolic activities in our body.
