penicillin structure He twisted ring in the upper region is called the beta lactam ring; it is the active area of the penicillin molecule. Every type of penicillin has the same beta lactam ring. Below is a chemical structure for the penicillin G molecule penicillin structure, in roughly the same form as the image to the right. (Molecule rendered on an SGI Indigo 2 with Spartan) The sodium or potassium after the drug indicates which salt the penicillin is bound to. The different types of penicillin differ in the the absorption rates penicillin structure, excretion rates penicillin structure, protein binding penicillin structure, availability and fluid volume through which the drug is distributed. Penicillin G is the most active by weight of the different types b penicillin structure.
penicillin structure Ut more likely to be administered by injection. Both forms can be damaged by the acidity of the stomach penicillin structure, but penicillin G is more sensitive. Because it is so sensitive penicillin structure, penicillin should be taken on an empty stomach. ActionPenicillin acts on bacteria by preventing cell wall formation. Once it is distributed throughout the body penicillin structure, it is taken up into bacterial cells. When these cells try to divide and form more cells penicillin structure, penicillin bonds irreversibly to a key enzyme for cell wall production. This bonding occurs on the area of the molecule between the sodium and nitrogen atoms on the structure shown above. That area is called the beta-lactam ring. Shown below is a graphical represntation of how the beta-lactam ring bonds to the necessary enzyme. Because penicillin prevents cell wall formation penicillin structure, it is more effective at interfering with bacteria while they are actively dividing. Bacterial that are at rest are not affected as strongly by penicillin. Since viruses do not have cell walls penicillin structure, they are not susceptible to penicillin. The following table shows various types of pathogens that can be treated by using either penicillin G or penicillin V.
