Menaquinone 8

Description:

Menaquinone 8, also known as MK-8, is a form of vitamin K2, which is part of the larger family of compounds known as menaquinones. It is characterized by its long isoprenoid side chain, which consists of eight repeating units, contributing to its lipid-soluble nature. Menaquinone 8 plays a crucial role in various biological processes, particularly in the synthesis of proteins involved in blood coagulation and bone metabolism. It is synthesized by certain bacteria and can be found in fermented foods, particularly natto, as well as in animal products. MK-8 is known for its antioxidant properties and potential health benefits, including supporting cardiovascular health and bone density. Its chemical structure includes a naphthoquinone core, which is essential for its biological activity. Menaquinone 8 is stable under normal conditions but can be sensitive to light and heat, which may affect its efficacy. As a dietary supplement, it is often used to enhance vitamin K levels in the body, particularly in individuals with dietary deficiencies.

Menaquinone 8

CAS: 523-38-6

Menaquinone 8 is a bacterial vitamin that is needed for the reduction of oxygen to water. It is a cofactor for the enzyme menaquinol:NAD+ oxidoreductase, which catalyzes the oxidation of menaquinol by NADH. Menaquinone 8 is found in bacteria and human liver, where it helps regenerate vitamin K2 (menadione) from vitamin K3 (menadiol). The ability of menaquinone 8 to reduce oxygen to water makes it an important factor in biological treatment methods such as wastewater treatment and radiation. Menaquinone 8 has been shown to be essential for health in children, as it helps maintain phospholipid membrane integrity in red blood cells.
