Which Vitamin is known as 'Coagulation Vitamin' ?

Question

Accepted Answer

Vitamin K is known as the 'Coagulation Vitamin' because it plays a crucial role in the process of blood clotting (coagulation). This vitamin is essential for the synthesis of certain proteins that are required for blood coagulation. Without adequate Vitamin K, the blood clotting process is impaired, which can lead to excessive bleeding. Vitamin K is involved in the carboxylation of specific glutamic acid residues on the proteins required for coagulation, which allows these proteins to bind calcium ions, a necessary step in the clotting process.

Now, let's examine why the other options are incorrect:

1. **Vitamin B_6**: This vitamin is primarily involved in protein metabolism, cognitive development, and the production of neurotransmitters. It does not play a direct role in blood coagulation, which is why it is not referred to as the 'Coagulation Vitamin'.

3. **Vitamin A**: Known for its role in maintaining healthy vision, immune function, and skin health, Vitamin A does not have a direct role in the coagulation process. Therefore, it is not associated with blood clotting.

4. **Vitamin C**: This vitamin is important for the synthesis of collagen, absorption of iron, and the maintenance of the immune system. While it has many vital functions, it is not directly involved in the coagulation process, and thus, it is not known as the 'Coagulation Vitamin'.

In summary, Vitamin K is specifically linked to the coagulation process, making it the correct answer as the 'Coagulation Vitamin'.
