The Mechanism of Oxygen Binding by Heme Proteins

Description
Changes in the visible spectrum of hemoglobin.

Spectra for hemoglobin in the deoxygenated state (blue trace) and the O2-bound state (red trace) are shown.

Hemoglobin in the deoxygenated state is a venous purple, whereas completely oxy-Hb is bright red.

As more O2 binds to Hb, the visible spectrum shifts from the blue to the red trace
