Structure & Reactivity
Cephaloridine is a cephalosporin compound with pyridinium-1-ylmethyl and 2-thienylacetamido side groups. The molecular nucleus, of which all cephalosporins are derivatives, is A3-7-aminocephalosporanic acid. Conformations around the β-lactam rings are quite similar to the molecular nucleus of penicillin, while those at the carboxyl group exocyclic to the dihydrothiazine and thiazolidine rings respectively are different.

Famous quotes containing the word structure:
“... the structure of our public morality crashed to earth. Above its grave a tombstone read, Be toleranteven of evil. Logically the next step would be to say to our commonwealths criminals, I disagree that its all right to rob and murder, but naturally I respect your opinion. Tolerance is only complacence when it makes no distinction between right and wrong.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 2, ch. 2 (1962)
