Which of these amino acids does not have an anomeric carbon atom
The term `Anomeric' carbon is used for a carbon atom in carbohydrates (Amino acids do not have anomeric carbon atom).
Formation of ring structure in carbohydrates (glucose and fructose) results in the creation of an additional asymmetric carbon, called anomeric carbon. This is responsible for a-and 13-anomerism.
However, if the question is repeated as such, go ahead with glycine because it does not contain asymmetric carbon (anomeric carbon atom is asymmetric carbon atom).
