Azioni biochim/fisiol

Vitamin K1 (Phylloquinone) is a lipid soluble polycyclic aromatic ketone used as a cofactor in the formation of coagulation factors II (prothrombin), VII, IX and X; anticoagulant factors protein C and S and as a cell signaling factor.

Vitamin K₁ plays a role as a cofactor in the synthesis of γ- carboxy glutamate (Gla), formation of coagulation factors II (prothrombin), VII, IX and X.
