CAS 523-39-7: Menaquinone 9

MK-9, a UV-sensitive vitamin K2 analog in bacteria like E. coli, binds to nitrate reductase in their electron transport chain.

Stability Light Sensitive, Temperature Sensitive Applications 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 variety 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. References Hugenholtz, P., et al.: J.

Menaquinone 9 is a vitamin K2 product, which is a naturally occurring compound found in fermented foods and certain animal products. It is a member of the menaquinone group, distinguished by the number of isoprene units in its side chain. Menaquinone 9 is synthesized by certain bacteria in the gut and absorbed through the intestines. Its primary mode of action involves serving as a cofactor for the enzyme gamma-glutamyl carboxylase, which is crucial for the post-translational modification of specific proteins required for calcium binding. Such processes are integral in the regulation of bone mineralization and cardiovascular health. Menaquinone 9's primary applications include its role in promoting bone strength and decreasing vascular calcification, thus potentially reducing the risk of osteoporosis and cardiovascular disease. Research on Menaquinone 9 has highlighted its potential advantages over other forms, such as enhanced bioavailability and longer half-life, which may lead to more sustained biological effects. This makes it a significant focus for studies into vitamin K2's expanding therapeutic potential and applications in clinical settings.
