“…The molecule (HCpx) contains NH 2 , C(O)NH, and C(O)OH groups, so it is similar in structure and acid-base properties to dipeptide molecules. Depending on the pH, cephalexin molecules exist in aqueous solution as positively charged H 2 Cpx + species, as HCpx − zwitterions, or as Cpx − , anionic, negatively charged entities [2].…”

“…The presence of -COOH, -CONH, -NH 2 moieties in the Cephalexin molecule and its inherent acid-base properties resemble to the dipeptide molecule. Depending upon the pH of aqueous medium, Cephalexin (denoted as CPX) can exist as cation (H 2 CPX þ ), zwitterion (HCPX À ) and anion (CPX À ) [31]. The zwitterion form of Cephalexin dominates within a pH range of 2.56-6.88 [32].…”
