Hemocyanins are copper-containing glycoproteins that serve as oxygen transport molecules in the blood of various invertebrates, including arthropods and mollusks. Unlike hemoglobin, which contains iron, hemocyanins utilize copper ions to bind oxygen, resulting in a blue color when oxygenated. These proteins are typically found dissolved in the hemolymph of these organisms and play a crucial role in respiratory gas exchange. Hemocyanins exhibit a high molecular weight and are composed of multiple subunits, which can vary in structure among different species. They are known for their ability to reversibly bind oxygen, allowing for efficient transport and release depending on the organism's metabolic needs. Additionally, hemocyanins can exhibit allosteric properties, meaning their oxygen-binding affinity can be influenced by factors such as pH and the presence of other ligands. Their evolutionary significance is notable, as they represent an ancient form of oxygen transport that predates the evolution of hemoglobin in vertebrates. Hemocyanins are also of interest in biochemistry and biotechnology for their unique properties and potential applications.
