DESCRIPTION
The nucleus of cephalexin is related to that of other cephalosporin
antibiotics. The compound is a
zwitterion; ie. the molecule contains both a basic and an acidic
group. The isoelectric point of
cephalexin in water is approximately 4.5 to 5.
The crystalline form of cephalexin which is available is a
monohydrate. It is a white crystalline solid
having a bitter taste. Solubility in water is low at room temperature;
1or 2 mg/mL may be dissolved
readily, but higher concentrations are obtained with increasing
difficulty.
The cephalosporins differ from penicillins in the structure of the
bicyclic ring system. Cephalexin
has a D-phenylglycyl group as substituent at the 7-amino position and
an unsubstituted methyl
group at the 3-position.
