APPLICATIONS
Side chain of Ampicillin, Cephalexin and Cephaclor. Cephalexin has D-phenylglycyl group as a substituent at the 7-amino position and an unsubstituted methyl group at the 3-position.

In chemistry, a side chain also often called R-group is a stable and covalently linked part attached to a core structure to modify and to gain different properties. Some examples of Cephalosporin side chains include:
