Uses

Different sources of media describe the Uses of 84-81-1 differently. You can refer to the following data:
1. 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-6 were the major isoprenoid quinones found in membrane preparations of Campylobacter jejuni and Campylobacter fetus.
