2021-04-08 · Vitamin K is essential for effective blood coagulation and plays a key role in synthesising certain clotting factors found in the clotting cascade. In the liver, it acts as a co-enzyme for γ-glutamyl carboxylase , an enzyme that converts the inactive forms of factors II (prothrombin), VII, IX and X into their active forms through the carboxylation of glutamic acid residues . Vitamin K is a fat-soluble vitamin which is essential in the human body for the purpose of blood coagulation as well as regulation of calcium metabolism in bones and other tissues. It plays an important role in the functioning of coagulation factors, osteocalcin, and matrix-Gla protein (1,2) and is a vital cofactor for the carboxylation of glutamate into ɤ-carboxyglutamate.

When chickens were fed a low-fat diet, they exhibited significantly lower coagulation capacity, resulting in severe bleeding [1]. Se hela listan på Se hela listan på Vitamin K is an essential bioactive compound required for optimal body function. Vitamin K can be present in various isoforms, distinguishable by two main structures, namely, phylloquinone (K1) and menaquinones (K2). The difference in structure between K1 and K2 is seen in different absorption rates, tissue distribution, and bioavailability. Vitamin K is a naturally occurring vitamin. Vitamin K is primarily found in leafy green vegetables such as spinach, broccoli, and lettuce, and enters your body when you eat these foods.

Vitamin k coagulation

Vitamin K was first identified in 1936 to be a key factor in blood clotting. When chickens were fed a low-fat diet, they exhibited significantly lower coagulation capacity, resulting in severe bleeding [1].

Vitamin K is a cofactor for the carboxylation of specific glutamic acid groups in coagulation factors II (prothrombin), VII, IX, and X. During this step, vitamin K is oxidized to vitamin K 2,3-epoxide. The anticoagulant drug warfarin acts as a vitamin K antagonist by inhibiting VKOR activity, hence preventing vitamin K recycling (see Coagulation).

The human body requires vitamin K for post-synthesis modification of certain proteins that are required for blood coagulation (K from koagulation, Danish for "coagulation") or for controlling binding of calcium in bones and other tissues. You get vitamin K from a variety of foods in your diet.
