prothrombin accelerator
Noun: A coagulation factor, specifically a protein present in blood plasma that is essential for the normal clotting of blood. It acts as an accelerator in the process that converts prothrombin into thrombin, a key step in the coagulation cascade.
This term is used in specialized medical and biological contexts, particularly in hematology, to discuss blood clotting mechanisms, deficiencies, or related disorders. - A deficiency in prothrombin accelerator can lead to a bleeding disorder. - The laboratory test measures the activity of prothrombin accelerator in the plasma.
- In Research Contexts: The term is used in scientific literature describing the biochemistry of hemostasis.
- The study focused on the gene encoding prothrombin accelerator.
- Factor V: This is the specific, more common name for prothrombin accelerator in standard coagulation nomenclature.
- Labile Factor: An older synonym for this coagulation factor.
- Proaccelerin: Another historical name for the same substance.
- Coagulation Factor V: The standard term in modern medical terminology.
- Factor V: The abbreviated form.
This term refers to a single, specific coagulation factor (Factor V). It is not a general term for any substance that accelerates prothrombin conversion. Its function is precisely defined within the classical coagulation cascade.
