Molecules of haemocyanin protein
Haemocyanin. Coloured transmission electron micro- graph (TEM) of molecules of haemocyanin, a respiratory protein and pigment found in molluscs and arthropods. Like haemoglobin in mammals, haemocyanin is an oxygen carrying molecule. Each molecule is barrel-shaped appearing rounded end-on but oblong with transverse striations when seen from the side. Here, the haemocyanin molecules are from a marine whelk Burnupena cincta. They are a copper- containing protein (non-porphyrin) that occurs in solution in mollusc haemolymph " blood". It is blue when oxygenated, colourless when de- oxygenated. Magnification: unknown

EDITORS COMMENTS
This print showcases the intricate beauty of haemocyanin protein molecules, a vital respiratory protein and pigment found in molluscs and arthropods. Similar to haemoglobin in mammals, haemocyanin serves as an oxygen-carrying molecule. The image reveals barrel-shaped structures that appear rounded when viewed end-on but oblong with transverse striations from the side. The featured haemocyanin molecules are derived from the marine whelk Burnupena cincta, highlighting their presence in the copper-containing protein solution within mollusc haemolymph or "blood". When oxygenated, these proteins exhibit a striking blue hue, which transforms into colorlessness when deoxygenated. The magnification used to capture this mesmerizing snapshot remains unknown; however, it undoubtedly amplifies our appreciation for the complexity and elegance of these molecular compounds. This photograph not only emphasizes the significance of biochemistry and proteomics but also offers a glimpse into the remarkable world of microscopic organisms. Science Photo Library presents this extraordinary visual representation as part of its extensive collection. It serves as a testament to both scientific exploration and artistic expression by capturing nature's wonders at an unseen level.
