Vitamin K2, also known as menaquinone 7, is a fat-soluble vitamin, commonly referred to as MK. Vitamin K2 is generally subdivided into the short-chain menaquinones (with MK-4 as the most important member) and the long-chain menaquinones, of which MK-7, MK-8 and MK-9 are nutritionally the most recognized. The activity of vitamin K2 is related to the length of the side chain, the longer the side chain, the better the absorption, the higher the biological activity, and the longer the presence in the blood.
Vitamin K2 is essential for the carboxylation of glutamate residues in certain proteins, to give carboxyglutamate.This modification allows the protein to bind calcium, an essential event in the blood clotting cascade. Carboxylation of glutamate is also important in other proteins involved in the mobilization or transport of calcium.
