During the course of her research career, Hodgkin published the first known three-dimensional structure of a steroid, cholesteryl iodide. Unbeknownst to anyone, penicillin crystals come in several shapes and Americans and British were working with four different types. Later, use of an IBM card-punch machine facilitated the laborious tasks of plotting the electron-density maps by which Hodgkin and her colleagues determined the molecular structure of penicillin. It came as a result of more than bch 3356 assignment 5 30 years of research following the first X-ray photographs in 1935. The structure of diamond confirmed the tetrahedral coordination of carbon as envisaged. At first, penicillin looked hopeless. It revolutionised physics and chemistry, and would do the same for biology. All this made such analysis an almost hopeless prospect, as the first photographs clearly showed.
