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 7 belongs to the class of K2-Vitamins homologs. Menaquinone 7 has been identified as the most bioactive cofactor for the carboxylation reaction of Gla-proteins such as osteocalcin and matrix-Gla protein, which plays a crucial role in building and maintaining overall bone health.
