Vitamin K is a family of structurally similar, fat-soluble vitamers found in foods and marketed as dietary supplements. [1] The human body requires vitamin K for post-synthesis modification of certain proteins that are required for blood coagulation ("K" from Danish koagulation, for "coagulation") or for controlling binding of calcium in bones and other tissues.

Blood coagulation pathways in vivo showing the central role played by thrombin. Health. Beneficial. Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot. It results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair.
Vitamin K reaction. Phytomenadione (Intravenous Vitamin K1) Vitamin K reactions are adverse side effects that may occur after injection with vitamin K. [1] The liver utilizes vitamin K to produce coagulation factors that help the body form blood clots which prevent excessive bleeding. [2][3] Vitamin K injections are administered to newborns as ...
Factor VII. Coagulation factor VII (EC 3.4.21.21, formerly known as proconvertin) is a protein involved in coagulation and, in humans, is encoded by gene F7. It is an enzyme of the serine protease class. Once bound to tissue factor released from damaged tissues, it is converted to factor VIIa (or blood-coagulation factor VIIa, activated blood ...
Vitamin K may help prevent coronary ... “It is best known for its role in helping blood clot, or coagulate, properly.” ... Blood clotting, or coagulation, is the process that helps your body ...
Gamma-glutamyl carboxylase is an enzyme that catalyzes the posttranslational modification of vitamin K -dependent proteins. Many of these vitamin K-dependent proteins are involved in coagulation so the function of the encoded enzyme is essential for hemostasis. [5] Most gla domain -containing proteins depend on this carboxylation reaction for ...
