Epimers are carbohydrates that differ in the location of the -OH group in one location. Both D-glucose and D-galactose are the best examples. D-glucose and D-galactose epimers create a single difference at C-4 carbon. They are not enantiomers, they are just epimers, or diastereomers, or isomers.

Anomers are cyclic monosaccharides or glycosides, differing from each other in the configuration of C−1 if they are aldose or in the configuration at C−2 if they are ketose.

Mutarotation is a difference in the specific rotation of plane-polarized light due to the change in the equilibrium between two anomers in the solution. Any molecule to show mutarotation must have a hemiketal or hemiacetal group.

Structure Of Glucose and Fructose - Structure of Glucose can be represented either as an open chain or if folded into a ring known as pyranose ring. Fructose is a ketohexose sugar. The Cyclic Structure of Fructose formed is called a hemiketal, and the five-membered ring that is formed is called a furanose ring.

Q. α anomer of an aldohexose E has a specific rotation of 120∘ while β anomer of E has a specific rotation of 80∘. If an equilibrium mixture of α,β anomers of E has the specific rotation of 96∘, then what will be percentage of the α -anomer in the equilibrium mixture assuming the concentration of the open structure is almost negligible?

Isomerism in organic chemistry is a phenomenon shown by two or more organic compounds having the same molecular formula but different properties due to difference in arrangement of atoms along the carbon skeleton (structural isomerism) or in space (Stereo isomerism)

Conclusion Among structural isomers and stereoisomers, stereoisomers are optical active due to their presence of chiral centres. The main difference between diastereomers and enantiomers is that the former is not a mirror image but the latter is a mirror image. Recommended Videos Enantiomers and Diastereomers

Amino acids are building blocks of proteins that play many important roles in the body. Technically, amino acids are organic compounds that contain the amine and carboxyl functional groups along with a side chain which is specific to each amino acid. Based on the body’s capability to synthesize, amino acids can be categorized into 2 types – essential amino acids and nonessential amino ...

The correct option is D isomers of glucose that differ in configuration at carbon one (C - 1) Anomers are diastereoisomers of cyclic forms of sugars or similar molecules differing in the configuration at the anomeric carbon (C-1 atom of an aldose or the C-2 atom of a 2-ketose).

Enantiomers - Enantiomers are a pair of molecules that exist in two forms that are mirror images of one another but cannot be superimposed one upon the other. Enantiomers are in every other respect chemically identical. Visit BYJUS to learn more about it.
