Hazard Information

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.
