Haemoglobin molecule. Computer artwork showing the structure of a haemoglobin molecule. Haemoglobin is a metalloprotein that transports oxygen around the body in red blood cells. Each molecule consists of iron-containing haem groups and globin proteins. Each globin protein is wrapped around a haem group, protecting it from being oxidised and destroyed by the oxygen it is intended to transport. The iron within each haem group reversibly bonds to oxygen and carbon dioxide in the blood. Four haemoglobin monomers (green, beige, purple, blue) usually bind together to form one large haemoglobin molecule (as shown here)

EDITORS COMMENTS
This print titled "Irregular Heartbeat, Conceptual Image" showcases the intricate structure of a haemoglobin molecule. Created through computer artwork, it beautifully illustrates how haemoglobin functions as a metalloprotein responsible for transporting oxygen throughout our bodies via red blood cells. The image reveals the composition of this vital molecule, consisting of iron-containing haem groups and globin proteins. The protective nature of each globin protein is highlighted in the artwork as it wraps around a haem group, shielding it from oxidation and destruction caused by the very oxygen it carries. Within each haem group lies an iron atom that forms reversible bonds with both oxygen and carbon dioxide present in our bloodstream. In this visual representation, four distinct monomers of different colors - green, beige, purple, and blue - come together to form one large haemoglobin molecule. This complex arrangement emphasizes the unity required for efficient oxygen transport within our bodies. Through its scientific lens, this mesmerizing photograph offers us a glimpse into the remarkable intricacies that sustain human life. It reminds us of the delicate balance maintained by these microscopic structures within us every day – ensuring that we receive adequate amounts of life-sustaining oxygen while protecting itself from potential harm.
