vitamin K Fat‐soluble vitamin essential for the synthesis of
γ‐carboxyglutamate in prothrombin and other proteins involved in the
blood clotting system, and bone proteins. Deficiency causes impaired blood coagulation and haemorrhage. Two groups of compounds have vitamin K activity: phylloquinones, found in green plants, and a variety of menaquinones synthesized by intestinal bacteria. Dietary deficiency is unknown, except when associated with general malabsorption diseases. However, some new‐born infants are at risk of haemorrhage as a result of low vitamin K status, and it is general practice to give a single, relatively large dose of the vitamin shortly after birth.
