What does OVH mean in UNCLASSIFIED
OVH stands for Octopus Vulgaris Haemocyanin, which is a protein found in the blood of the common octopus, Octopus vulgaris. Haemocyanin is a type of respiratory protein that binds to oxygen and transports it throughout the body. It is similar to haemoglobin, which performs the same function in humans and other vertebrates.
OVH meaning in Unclassified in Miscellaneous
OVH mostly used in an acronym Unclassified in Category Miscellaneous that means Octopus Vulgaris Haemocyanin
Shorthand: OVH,
Full Form: Octopus Vulgaris Haemocyanin

Properties of OVH
- Structure: OVH is a hexameric protein with a molecular weight of approximately 360 kDa. It consists of six identical subunits, each of which contains a copper ion.
- Function: OVH binds to oxygen in a reversible manner. When oxygen levels are high, OVH transports oxygen to tissues throughout the body. When oxygen levels are low, OVH releases oxygen to meet the cells' metabolic needs.
- Oxygen Affinity: OVH has a lower oxygen affinity than haemoglobin. This allows the octopus to extract oxygen from the water more efficiently in low-oxygen environments.
Role in Octopus Physiology
OVH plays a vital role in the octopus's ability to survive in its unique environment. The octopus often inhabits oxygen-poor habitats, such as deep waters or crevices. OVH's low oxygen affinity enables the octopus to extract oxygen from even these low-oxygen environments.
Essential Questions and Answers on Octopus Vulgaris Haemocyanin in "MISCELLANEOUS»UNFILED"
What is OVH?
Octopus Vulgaris Haemocyanin (OVH) is a protein found in the blood of the common octopus (Octopus vulgaris) and other cephalopods. It is a respiratory protein that binds to oxygen molecules and transports them throughout the body. OVH is similar to haemoglobin in humans, which serves the same function.
What is the structure of OVH?
OVH is a large, multi-subunit protein with a molecular weight of around 3.5 million Da. It consists of 12 identical subunits, each of which contains a copper ion bound to a pair of histidine residues. The copper ions are the sites of oxygen binding.
How does OVH transport oxygen?
OVH binds to oxygen molecules in a reversible manner. When the oxygen concentration is high, OVH binds to oxygen and transports it to the tissues. When the oxygen concentration is low, OVH releases oxygen to the tissues.
What is the role of copper ions in OVH?
Copper ions are essential for the oxygen-binding function of OVH. The copper ions undergo a redox reaction when binding to oxygen, changing from the Cu(I) to the Cu(II) state. This reaction results in a conformational change in the OVH molecule, which allows it to bind to oxygen more tightly.
How is OVH different from haemoglobin?
OVH is different from haemoglobin in several ways. First, OVH contains copper ions, while haemoglobin contains iron ions. Second, OVH has a much higher affinity for oxygen than haemoglobin. Third, OVH is a multi-subunit protein, while haemoglobin is a single-subunit protein.
Final Words: OVH is a key protein involved in the respiration of the common octopus. Its unique properties allow the octopus to survive in diverse underwater habitats. Understanding the role of OVH provides insights into the physiological adaptations of marine organisms.
