what is the role of vitamin k in blood clotting?

Answer 1

Role of vitamin-K in blood clotting
Vitamin -K is a fat soluble vitamin and can act as cofactor. It is mainly found in green leafy vegetables and some times it is produced in the gastrointestinal tract of certain bacterias.It is helpful for synthesizing certain proteins that can be used for blood clotting. Vitamin-K have a key role in the coagulation process, they will be convert the coagulation factors into their mature forms. The vitaminK is not available, the clotting process do not occur. For example, if a wound formed and bleeding occurs ingest Vitamin-K they should be metabolized and then it should be utilised for the synthesis of mature coagulation factor. Vitamin-K is an important factor in coagulation cascade. Coagulation factors like ll,Vll,lX,and X are important in the intrinsic pathway of coagulation. Vitamin-K produces certain proteins such as protein-C, S and Z. These proteins will degrade certainvcogulation factors, it is helpful for preventing excessive thrombosis in the first coagulation cascade.
Vitamin-K deficiencies cause impaired coagulation, excessive bleeding and haemorrhage. So Vitamin-K is essential for the blood clotting.
