It has a high molecular weight and deficiency in Vitamin K or damage to the liver can disturb the blood clotting mechanism leading to an increase in bleeding. Lack of vitamin C, which clinically is the basic defect of scurvy, does not appear to cause a defect in blood coagulation while vitamin K affects the clotting mechanism by being essential for the production of four distinct clotting factors: prothrombin, factors VII, IX and X. This initiates blood clotting by binding to calcium atoms on. It's a very commonly used oral medication. 2. vitamine k is oxidized in this reaction. glutamic acid to form Gla. Blood clotting (technically "blood coagulation") is the process by which (liquid) blood is transformed into a solid state.
