Anomeric carbon is carbon on which anomers rotate. The carbonyl carbon found in the open chain becomes anomeric carbon in the crystallized structure, which is also the most iodized carbon found in the ring. Depending on the orientation of the group that is attached to the anomeric carbon, ketose carbohydrates and cyclized aldose can adopt either a or b anomeric configuration, states Emory University.
Anomeric carbon possesses a property known as anomeric effect, which is the preference for an electronegative to be at an axial orientation as opposed to the equatorial orientation. This explanation has also included carbohydrates, acyclic system and saturated heterocycles. It's known that electronegative at anomeric position exist as the axial performer. This is what is called anomeric effect. According to Biology Online, a good example of an anomeric carbon is carbon found in monosaccharide, like glucose, on which rotation occurs. In most cases the anomeric carbon can be identified by one carbon atom attached to two oxygen atoms and joined by single bonds. The result of this rotation is two distinct configurations, an alpha and a beta. As such, the carbohydrates are able to change spontaneously between the alpha and beta configurations, a process commonly referred to as mutarotation.
