essential substance of the original enzyme (factor B), and to participate in
the coagulation factor VII, IX, and X synthesis, to maintain the animal's blood
coagulation physiological process. Lack of vitamin K can cause the above
coagulation factor synthesis disorder, affecting the coagulation process and
cause bleeding. Vitamin K for the animal body (mainly refers to the presence in
the tissues and organs such as liver, bone, testis, skin and kidney) of vitaminK-dependent carboxylation system necessary, is an indispensable factor in the
process of bone protein (BGP) synthesis. In addition, in the high-energy

vitamin metabolism plays an important role, and with a diuretic, to enhance
liver detoxification function, and to participate in the structure of the
membrane, lowers blood pressure function.
