Phylloquinone is a polycyclic aromatic ketone, based on 2-methyl-1,4-naphthoquinone, with a 3-phytyl substituent.

It is a fat-soluble vitamin that is stable to air and moisture but decomposes in sunlight. It is found naturally in a wide variety of green plants.

Terminology

It is often called vitamin K₁^[1] or phytonadione. Sometimes a distinction is made with phylloquinone considered natural and phytonadione considered synthetic.^[2]

A stereoisomer of phylloquinone is called vitamin k₁ (note the difference in capitalization).

Mechanism

Its best known mechanism of action is as a cofactor in the formation of coagulation factors II (prothrombin), VII, IX and X by the liver. Vitamin K₁ is commonly used to treat warfarin toxicity, and an antidote for coumatetralyl. It is also required for the formation of anticoagulant factors protein C and S. Vitamin K is also required for bone protein formation.

Phylloquinone is an electron acceptor in the electron transport chain of chloroplasts.
