Metabolite Identification
Common NameVitamin K1
DescriptionVitamin K1, also known as phylloquinone or phytonadione, is a polycyclic aromatic ketone, based on 1,4-naphthoquinone, with 2-methyl and 3-phytyl substituents. Vitamin K is a family of phylloquinones that contain a ring of 2-methyl-1,4-naphthoquinone and an isoprenoid side chain. Several forms of vitamin K have been identified: vitamin K1 derived from plants, vitamin K2 (menaquinone) from bacteria and synthetic naphthoquinone provitamins, and vitamin K3 (menadione). Vitamin K1 has only one double bond on the proximal isoprene unit. Vitamin K1 possesses the same type and degree of activity as does naturally-occurring vitamin K, which is necessary for the production via the liver of active prothrombin (factor II), proconvertin (factor VII), plasma thromboplastin component (factor IX), and Stuart factor (factor X). Rich sources of vitamin K1 include green plants, algae, and photosynthetic bacteria. Vitamin K1 has antihemorrhagic and prothrombogenic activity. Vitamin K1 is a fat-soluble vitamin that is stable to air and moisture but decomposes in sunlight. Vitamin K1 is an antidote for coumatetralyl.

General function:
Involved in gamma-glutamyl carboxylase activity
Specific function:
Mediates the vitamin K-dependent carboxylation of glutamate residues to calcium-binding gamma-carboxyglutamate (Gla) residues with the concomitant conversion of the reduced hydroquinone form of vitamin K to vitamin K epoxide.
