[Description]

Menaquinone 9 (MK-9) is a vitamin K2 analog that has been found in various bacteria, including E. coli. MK-9 is UV-sensitive and binds to soluble nitrate reductase, a component of the bacterial electron transport chain. In vivo, MK-9 increases plasma prothrombin concentration in vitamin K-deficient rats.
[Chemical Properties]

Light Yellow to Yellow Solid
[Uses]

Menaquinones are isoprenoid quinones of the naphthalene series and belongs to the K2 Vitamin homologs. Menaquinones were originally discovered as the anti-hemorrhagic factor and now encompasses a vari ety of physiological processes. Menaquinone 9 is a form of vitamin K2 which acts as a prothrombogenic agent and is also a functional electron transfer component in nitrate reductase.
[Uses]

Vitamin (prothrombogenic).
[Definition]

ChEBI: Menaquinone-9 is a menaquinone whose side-chain contains 9 isoprene units in an all-trans-configuration. It has a role as an Escherichia coli metabolite.
