Concept explainers
(a)
Interpretation:
For the given cyclicmonosaccharide, acetal / hemiacetal carbon, anomeric carbon **a or β anomeric nature should be decided.
Concept introduction:
When an alcohol and ether group are attached to the same carbon, it is called as the hemiacetal carbon. When 2 ether groups are attached to the same carbon, it is called as the acetal carbon.
Two anomers exists as alpha (a) ** beta (β), depending on the differences in the bond arrangement around the anomeric carbon.
(b)
Interpretation:
For the given monosaccharide, acetal / hemiacetal carbon, anomeric carbon **a or β anomeric nature should be decided.
Concept introduction:
When an alcohol and ether group are attached to the same carbon, it is called the hemiacetal carbon. When 2 ether groups are attached to the same carbon, it is called as the acetal carbon.
Two anomers exists as alpha (a) ** beta (β), depending on the configurational differences in the anomeric carbon of a monosaccharide.
