Description
Vitamin K2 is a naturally occurring vitamin that contains the basic structure of menaquinone and has anti-hemorrhagic effects. It is a yellow crystal or oily liquid at room temperature, insoluble in water, easily soluble in organic solvents and vegetable oils, and heat-resistant, but easily destroyed by light. It can promote the synthesis of prothrombinogen by liver and regulate the synthesis of coagulation factors VII, IX and X, thus accelerating blood coagulation.
