Menaquinone-9 is a prominent member of a series of menaquinones vitamin K 2 produced by intestinal bacteria and menadione vitamin K 3 is a synthetic compound that can be converted to menaquinone-4 by animal tissues. Vitamin K 3 provitamins after being alkylated in vivo exhibit the antifibrinolytic activity of vitamin K.

Vitamin K which is needed for blood clotting can be derived from plants bacteria and animal tissues. What form of vit K is produced by bacteria in the distal colon. Menaquinones which are predominantly of bacterial origin are present in modest amounts in various animal-based and fermented foods 14.

The carboxylation reaction is driven by a vitamin K-dependent carboxylase activity reaction 1 which simultaneously converts vitamin K quinol to vitamin K 23-epoxide.
