Vitamin K refers to a group of fat-soluble vitamins that play a role in blood clotting, bone metabolism, and regulating blood calcium levels. The body needs vitamin K to produce prothrombin, a protein and clotting factor that is important in blood clotting and bone metabolism. The only known biological role of Vitamin K is for a Vitamin K-dependent carboxylase that catalyzes the carboxylation of the amino acid, glutamic acid which thus produces gamma carboxyglutamic acid (Gla) as a result. Some functions requiring Vitamin K include Blood Clotting, Bone Mineralization, and Cell Proliferation. The active form of vitamin K needed for carboxylation is the reduced form, vitamin K quinol. Known enzyme reactions are numbered 1, 2, and 3. The carboxylation reaction is driven by a vitamin K-dependent carboxylase activity (reaction 1) which simultaneously converts vitamin K quinol to vitamin K 2, 3-epoxide. Vitamin K is found in the following foods: Green leafy vegetables, such as kale, spinach, turnip greens, collards, Swiss chard, mustard greens, parsley, romaine, and green leaf lettuce. Vegetables such as Brussels sprouts, broccoli, cauliflower, and cabbage. liver disease
