Computer graphics of haemoglobin molecule

Computer graphic representation of part of the haemoglobin molecule, the oxygen-carrying substance of human blood, showing its four polypeptide (protein) chains. The protein component of haemoglobin combines with four haem groups (iron-containing porphyrin substances), shown here in green & red. Haemoglobin has the ability to combine reversibly with oxygen, taking it up in the lungs and releasing it through the tissues. Red blood cells (erythrocytes) are literally packed with haemoglobin, containing only very small amounts of other substances

Haemoglobin Polypeptide Red Blood Cell Cells

EDITORS COMMENTS
This print showcases a stunning computer graphic representation of a vital component in our blood - the haemoglobin molecule. The intricate structure of this oxygen-carrying substance is beautifully depicted, revealing its four polypeptide chains that form an integral part of its composition. Highlighted in vibrant shades of green and red are the four haem groups, which contain iron-containing porphyrin substances. These groups play a crucial role in enabling haemoglobin to bind with oxygen reversibly, facilitating the transportation of this life-sustaining gas from our lungs to every tissue within our bodies. The image also sheds light on the incredible abundance of haemoglobin within red blood cells (erythrocytes). These cells are literally packed with this remarkable protein, containing only minute quantities of other substances. This emphasizes just how essential haemoglobin is for ensuring efficient oxygen delivery throughout our entire system. Through molecular computer graphics, Science Photo Library has brought forth an awe-inspiring visual representation that not only showcases the complexity and beauty inherent in human anatomy but also highlights the intricate mechanisms at work within our own bodies. It serves as a powerful reminder of the extraordinary design and functionality present within us all.
