Vitamin K is involved in the activation through carboxylation of a number of proteins involved in calcium binding and which are relevant to blood clotting, bone formation and in vascular tissue metabolism. It is the cofactor of the enzyme that carries out the carboxylation. The active part of vitamin K is the naphtoquinone ring that it contains.
