Vitamin K is the family name for a series of fat-soluble compounds, which have a common 2-methyl-1, 4-naphthoquinone nucleus but differ in the structures of a side chain at the 3-position. They are synthesised by plants and bacteria. In plants the only important molecular form is phylloquinone (vitamin K1), which has a phytyl side chain. Bacteria synthesise a family of compounds called menaquinones (vitamin K2), which have side chains based on repeating unsaturated 5-carbon (prenyl) units.
