Menaquinone 7 Chemical Properties,Uses,Production
Description
Menaquinone 7 (MK-7) is a vitamin K2 analog that has been found in a variety of fermented foods. It increases osteocalcin, osteoprotegerin, and RANKL mRNA expression in osteoblastic MC3T3E cells. MK-7 (1 μM) increases alkaline phosphatase activity and calcium content in femoral-metaphyseal tissues isolated from normal and skeletal-unloaded rats. In vivo, MK-7 (100 μg/g diet) inhibits aortic and myocardial calcification and decreases aortic alkaline phosphatase tissue concentrations in a rat model of extraosseous calcification. It also increases trabecular number, bone mineral density, and bone mineral content in a rat model of ovariectomy-induced bone loss.
Chemical Properties
Light Yellow Crystalline Solid
Uses
Vitamin (prothrombogenic)
Definition
ChEBI: A menaquinone whose side-chain contains seven isoprene units in an all-trans-configutation.
General Description
Vitamin K2, also known as menaquinone, is a polyisoprenoid-substituted?napthoquinone. Menaquinone-7 (MK-7) is a subtype of vitamin K2. It is found in animals, soy protein, fermented products and is primarily produced by bacteria.
Vitamin K2 (MK-7)-(5,6,7,8-d4,2-methyl-d3) is a deuterated vitamin K2 wherein C-5, C-6, C-7, C-8, and 2-methyl protons are replaced by deuterium.
Side effects
Menlaquinone 7 is usually well tolerated and side effects are rare. Mild digestive symptoms, such as nausea, bloating or diarrhoea, may occur with overdose, but these side effects are usually temporary and will subside on their own. There have been some reports of allergic reactions to Vitamin K2 MK7, including skin rashes and breathing difficulties. As Menlaquinone 7 interferes with the action of blood thinners such as warfarin. Therefore, if you are taking blood thinners, be sure to consult your healthcare provider before taking Vitamin K2 MK7 or any other vitamin or supplement. Therefore, if you are taking blood thinners, be sure to consult your healthcare provider before taking Vitamin K2 MK7 or any other vitamin or supplement.
Source
Vitamin K2, such as Menaquinone 7 (MK-7), can be obtained through natural fermentation and is shown to be the most superior form of K2. The main sources of menaquinones include animal-based foods like meat, fish, dairy products, etc. Short-chain menaquinones like MK-4 (having four isoprene units) are found majorly in animal-based food products. Menaquinones having long chains such as MK-7 to MK-13 are primarily synthesized by bacteria that include species of aerobic, anaerobic, facultative, as well as obligate anaerobic bacterial species that include Bacillus, Corynebacterium, Escherichia, Lactococcus and Vibrio. Some of these bacterial species are present as microflora in the gut. MK-7 or K2-7 is present in very high concentrations in a Japanese traditional food called natto. Natto is made by fermenting soybeans using Bacillus subtilis. Another source of menaquinones is the microflora of the intestine. Although intestinal synthesis has been shown to produce significant quantities of menaquinones, absorption from this source is inefficient to fulfill the required quantities. Menaquinone is analogous to ubiquinone in function as ubiquinone also contains isoprenoid side chains of varying lengths and, therefore, is used as an electron carrier in the electron transport chain by bacteria. Vitamin K2-7 is also detected in human milk samples depending on dietary intake[1].
