    K vitamins play an essential role as cofactor for the enzyme -glutamyl carboxylase, which is involved in vitamin k-dependent carboxylation of the , besides being essential for the function of the protein, is also an important vitamin recovery mechanism since it serves as a recycling pathway to recover vitamin k from its epoxide metabolite (ko) for reuse in carboxylation. Mk-4 by the animal from k , or may be of bacterial origin (mk-7, mk-9, and other mks). Menaquinone-4 (also known as in certain animal tissues (arterial walls, pancreas, and testes) by replacement of the phytyl tail with an unsaturated geranylgeranyl tail containing four menaquinone-7 and other long-chain menaquinones are different from mk-4 in that they are not produced by human tissue. This process has been shown to be dependent upon the action of k vitamins. Among consequences of anticoagulant treatment increased aortic wall stiffness, coronary insufficiency, ischemia, and even heart failure. K (menaquinone-7) and gamma-carboxylated osteocalcin concentration in normal individuals. Gas6 is secreted by leucocytes and endothelial cells in response to injury and helps in cell survival, proliferation, migration, and adhesion. Mk-4 and mk-7 are both found in the united states in dietary supplements for bone health. There are no substantial differences in mk-4 levels between wild game, free-range animals, and factory farm animals. Traditionally, k vitamins were recognized as the factor required for coagulation, but the functions performed by this vitamin group were revealed to be much more complex.
