TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 370(SRC), determined from a log Kow of 2.20(2) and a regression-derived equation(3), indicates that menadione is expected to have moderate mobility in soil(SRC). Volatilization of menadione from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.1X10-9 atm-cu m/mole(SRC), using a fragment constant estimation method(4). Menadione is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.9X10-4 mm Hg(SRC), determined from a fragment constant method(5).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 370(SRC), determined from a log Kow of 2.20(2) and a regression-derived equation(3), indicates that menadione is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 3.1X10-9 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF of 1.4(SRC), from its log Kow(2) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), menadione, which has an estimated vapor pressure of 1.9X10-4 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), will exist in the vapor phase in the ambient atmosphere. Vapor-phase menadione is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 33 hrs(SRC), calculated from its rate constant of 1.1X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Menadione is decomposed by sunlight(4).

Menadione (vitamin K3) is involved as a cofactor in the posttranslational gamma-carboxylation of glutamic acid residues of certain proteins in the body. These proteins include the vitamin K-dependent coagulation factors II (prothrombin), VII (proconvertin), IX (Christmas factor), X (Stuart factor), protein C, protein S, protein Zv and a growth-arrest-specific factor (Gas6). In contrast to the other vitamin K-dependent proteins in the blood coagulation cascade, protein C and protein S serve anticoagulant roles. The two vitamin K-dependent proteins found in bone are osteocalcin, also known as bone G1a (gamma-carboxyglutamate) protein or BGP, and the matrix G1a protein or MGP. Gamma-carboxylation is catalyzed by the vitamin K-dependent gamma-carboxylases. The reduced form of vitamin K, vitamin K hydroquinone, is the actual cofactor for the gamma-carboxylases. Proteins containing gamma-carboxyglutamate are called G1a proteins.

The Koc of menadione is estimated as 370(SRC), using a log Kow of 2.20(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that menadione is expected to have moderate mobility in soil.

Menadione's production and use in medicines and animal feed additives(1) may result in its release to the environment through various waste streams(SRC). Its former production and use in fungicides(1) may have resulted in its direct release to the environment(SRC).

An estimated BCF of 1.4 was calculated for menadione(SRC), using a log Kow of 2.20(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

Deficiency may occur in the following persons or conditions: Patients receiving total parenteral nutrition (TPN); in malabsorption syndromes associated with pancreatic insufficiency (including cystic fibrosis), hepatic-biliary tract disease (obstructive jaundice, internal biliary fistula), diseases of the small intestine (celiac disease, tropical sprue, regional enteritis, ulcerative colitis, persistent diarrhea or dysentery, short bowel syndrome after extensive bowel resection); prolonged T-tube drainage; abetalipoproteinemia; infants receiving substitute formulas and those who are breast-fed. /Vitamin K/

The chief clinical manifestation of vitamin K deficiency is an increased tendency to bleed. Ecchymoses, epistaxis, hematuria, gastrointestinal bleeding, and postoperative hemorrhage are common; intracranial hemorrhage may occur. /Vitamin K/

Menadione (Vitamin K3) is a fat-soluble vitamin precursor that is converted into menaquinone in the liver. Vitamin K1 and K2 are the naturally occurring types of vitamin K. The former, which is also known as phylloquinone, is synthesized by plants and can be found in such foods as spinach, broccoli, lettuce, and soybeans. The latter, sometimes alternatively referred to as menaquinone, is primarily produced by bacteria in the anterior part of the gut and the intestines. Vitamin K3, on the other hand, is one of the many manmade versions of vitamin K. Also called menadione, this yellowish, synthetic crystalline substance is converted into the active form of the K2 vitamin inside of the animal body. While a vitamin K deficiency can be dangerous, especially to infants that may easily suffer from extensive hemorrhaging, an overdose can be as equally detrimental. Newborns that are administered too great a dosage of vitamin K3 can suffer from kernicterus, a form of severe brain damage that may produce decreased movement, loss of appetite, seizures, deafness, mental retardation, and even death. This condition is associated with an abnormally high concentration of bilirubin, a bile pigment, in the tissues of the brain, which can be caused by the presence of K3. For this reason, K3 is less often utilized medically than it was in former times.

Menadione (vitamin K3) is involved as a cofactor in the posttranslational gamma-carboxylation of glutamic acid residues of certain proteins in the body. These proteins include the vitamin K-dependent coagulation factors II (prothrombin), VII (proconvertin), IX (Christmas factor), X (Stuart factor), protein C, protein S, protein Zv and a growth-arrest-specific factor (Gas6). In contrast to the other vitamin K-dependent proteins in the blood coagulation cascade, protein C and protein S serve anticoagulant roles. The two vitamin K-dependent proteins found in bone are osteocalcin, also known as bone G1a (gamma-carboxyglutamate) protein or BGP, and the matrix G1a protein or MGP. Gamma-carboxylation is catalyzed by the vitamin K-dependent gamma-carboxylases. The reduced form of vitamin K, vitamin K hydroquinone, is the actual cofactor for the gamma-carboxylases. Proteins containing gamma-carboxyglutamate are called G1a proteins.

The vitamin K-dependent blood clotting factors, in the absence of vitamin K (or in the presence of the coumarin type of anticoagulant), are biologically inactive precursor proteins in the liver. Vitamin K functions as an essential cofactor for a microsomal enzyme system that activates these precursors by the conversion of multiple residues of glutamic acid near the amino terminus of each precursor to gamma-carboxyglutamyl residues in the completed protein. The formation of this new amino acid, gamma-carboxyglutamic acid, allows the protein to bind Ca+2 and in turn to be bound to a phospholipid surface, both of which are necessary in the cascade of events that lead to clot formation. /Vitamin K/

Vitamin k is necessary for formation of prothrombinogen and other blood clotting factors in liver. During clotting, circulating prothrombin is required for production of thrombin; in turn, thrombin converts fibrinogen to fibrin, network of which constitutes clot. /vitamin k/

The active form of vitamin K appears to be the reduced vitamin K hydroquinone, which, in the presence of oxygen, carbon dioxide, and the microsomal carboxylase enzyme, is converted to its 2,3-epoxide at the same time gamma-carboxylation takes place. The hydroquinone form of vitamin K is regenerated from the 2,3-epoxide by a coumarin sensitive epoxide reductase ... . /Vitamin K/

Menadione is a potent inhibitor of aldehyde oxidase (Ki ~0.1 uM) and can be used together with allopurinol to discriminate between aldehyde oxidase- and xanthine oxidase-catalyzed reactions.
