Vitamin K is a cofactor in the post-ribosomal synthesis of clotting factors, including factor II (prothrombin), VII (proconvertin), IX (plasma thromboplastin component), and X (Stuart factor), as well as proteins C and S, which are involved in the production and inhibition of thrombin. Vitamin K hypovitaminosis results in hypoprothrombinemia, leading to prolonged bleedings, large hematomas, severe hemorrhagic anemia, and hemolytic jaundice. Menadione (synthetic vitamin K3) is absorbed in the distal small intestine and colon, metabolized to the diol (hydroquinone) form, and excreted as glucuronide and sulfate conjugates.
