As a coenzyme of carboxylase, it participates in the synthesis of coagulation factors II, VII, IX, and X, allowing the glutamic acid residues on these factors to form gamma-carboxyglutamic acid, which has the ability to bind to Ca2 and connect to the phospholipid surface and regulatory proteins to produce coagulation. If it is lacking or the epoxide reduction reaction is blocked, the prothrombin time will be prolonged, causing bleeding.
