A molecular model of penicillin G,a version of the penicillin antibiotic that is administered intravenously to treat syphilis,meningitis,endocarditis,pneumonia,septicaemia in children,septic arthritis,gangrene,gonorrhoea,and diphtheria. Since penicillin G is injected rather than taken orally,the drug bypasses the acidic contents of the stomach,allowing higher concentrations of the drug to increase antibiotic activity. Atoms are coloured dark gray (carbon),light gray (hydrogen),red (oxygen),blue (nitrogen),and yellow (sulfur) |
