What is the Difference Between Clotting Factor 8 and 9?
🆚 Go to Comparative Table 🆚Clotting factors 8 and 9 are proteins involved in the blood coagulation process. The main differences between them are:
- Function: Clotting factor 8 is a cofactor that associates with clotting factor 9 to ensure the activation of clotting factor 10. Clotting factor 9 is a serine protease enzyme that cleaves and activates clotting factor 10 in the coagulation process.
- Hemophilia: A low level of clotting factor 8 causes hemophilia A disease, while a low level of clotting factor 9 causes hemophilia B (Christmas) disease.
- Limbic Structure: Clotting factor 8 is composed of 26 exons and encodes a mature protein of 2,332 amino acids. Factor IX, on the other hand, contains only eight exons.
- Treatment: Both clotting factors are involved in the coagulation cascade reaction, which helps stop bleeding. Their deficiencies can lead to hemophilia, an inherited bleeding disorder in which the blood does not clot properly. This can result in spontaneous bleeding as well as bleeding following injuries or surgery. Treatment for both disorders involves replacing the missing or reduced clotting factor with clotting factor concentrates.
In summary, clotting factors 8 and 9 play different roles in the coagulation process, and their deficiencies result in different types of hemophilia. Both proteins are involved in the coagulation cascade, but their structures and functions are distinct.

Comparative Table: Clotting Factor 8 vs 9
Clotting factors 8 and 9 are both involved in the blood clotting process, but they have distinct roles and characteristics. Here is a table highlighting the differences between clotting factor 8 and clotting factor 9:
Feature | Clotting Factor 8 | Clotting Factor 9 |
---|---|---|
Function | Cofactor for clotting factor 9a | Serine protease enzyme that cleaves and activates clotting factor 10 |
Role in Blood Clotting | Associates with clotting factor 9 to ensure the activation of clotting factor 10 | Cleaves prothrombin in two places to make thrombin |
Thrombin Production | Involved in the formation of the tenase complex, which ultimately results in blood clot formation | Converts soluble fibrinogen into insoluble strands of fibrin, which act as a blood clot |
Relationship with Other Clotting Factors | Forms a complex with Ca2+ and phospholipids in the presence of clotting factor 9a | Activated by thrombin, which is produced from the action of clotting factor 8 and clotting factor 9a |
Both clotting factors 8 and 9 are produced by the liver and play crucial roles in the blood clotting process.
