Cubic close-packed crystal structure
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 showcases the intricate structure of a haemoglobin molecule, depicted through computer artwork. Haemoglobin is a vital metalloprotein responsible for transporting oxygen throughout our bodies within red blood cells. Composed of iron-containing haem groups and globin proteins, each molecule safeguards the haem group from oxidation caused by the very oxygen it carries. The iron within each haem group forms reversible bonds with both oxygen and carbon dioxide present in our bloodstream. In this image, we witness four individual haemoglobin monomers, distinguished by their vibrant colors of green, beige, purple, and blue. These monomers typically unite to form one large and complex haemoglobin molecule as portrayed here. The visual representation allows us to appreciate the precise arrangement and close-packed cubic crystal structure that characterizes this essential protein. Through its detailed portrayal of molecular biology, this photograph offers us a glimpse into the fascinating world of life's building blocks at an atomic level. Science Photo Library has masterfully captured this scientific wonder in stunning detail without mentioning any commercial use or affiliation with any company. It serves as a testament to the beauty found within nature's most fundamental components while reminding us of the incredible complexity that underlies even our most basic bodily functions.
