Former Display Label: 'The structure of penicillin'

The structure of penicillin was worked out using X-ray crystallography. The leading contributor in this research was the Oxford scientist Dorothy Hodgkin who took up the problem in 1942. She was awarded the Nobel Prize in Chemistry in 1964.

The model gives a three dimensional map of part of one of the crystal salts of penicillin. The contours are lines of electron density and show the positions of individual atoms in the structure. The diagram shows two schematic views of the structure.
