Haemoglobin model, with four movable sections, built in 1967, by Max Perutz
This model of haemoglobin was built in 1967 by Max Perutz (1914-2002) at the Laboratory of Molecular Biology in Cambridge.
In 1937 Perutz began to use X-ray diffraction to uncover the biological function of haemoglobin, the protein in red blood cells responsible for transporting oxygen. It took nearly twenty years for him to painstakingly solve this complex structure.
This model was used in research to understand and compare the basic structure of the molecule to understand how it transported oxygen around the body.
