We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

3D Printed Physical Model of Hemoglobin
Shown below is a physical 3D printed model of Hemoglobin, based on the structure 1a3n.pdb. The two alpha-globin chains are colored light red, the two beta globin chains are colored dark red, and the four heme groups are colored yellow.
