About Vitamin K
A fat-soluble vitamin, Antihemorrhagic.
Mechanism of Action of Vitamin K
Phytonadione (Vitamin K1) is a synthetic form of vitamin K and is lipid-soluble. Vitamin K acts as a cofactor in the synthesis of coagulation proteins; prothrombin, factors VII, IX, and X by the liver. Vitamin K dependent changes in the final stage of synthesis of these coagulation proteins is gama-carboxylation of glutamate residues of these zymogen proteins and their descarboxy-forms converted into active forms; which confers on them the capacity to bind Ca2+ and to get bound to the phospholipid surfaces which are essential properties for participation in the coagulation cascade.
