The monosaccharide having anomeric carbon atoms are

Options

A. geometrical isomers
B. `alpha` and `deta-optical` isomers
C. having symmetrical carbon atoms
D. None of the above

Answer

B

Explanation

`C_(1)` carbon of monosaccharides is called anoneric carbon. When `-OH` group is attached with `C_(1)` carbon towards right , it is called `alpha-foem` and when` -OH ` group is towards left , it is called `beta`-form , such pair or optical isomers which differ in the configuration only around anoneric carbon are called anomers.
