Penicillin drug molecule

Penicillin. Computer graphic of part of a molecule of penicillin, an antibiotic drug. The spheres represent atoms and are colour-coded as: carbon (green), oxygen (red), hydrogen (white), nitrogen (blue) and sulphur (yellow). The atoms are joined by atomic bonds. Penicillin, like all antibiotics, is an anti-bacterial drug. Penicillin was discovered by Alexander Fleming in 1928 after he observed that Penicillium notatum mould prevented the growth of bacteria. Since then, many types of penicillins from a range of fungi have been isolated and manufactured for medical use. Graphic of a molecule from a Penicillium sp. mould
