Animals may also convert it to vitamin K 2, variant MK-4. Vitamin K plays a biological role as a cofactor of gamma glutamyl carboxylase, which mediates - carboxylation of glutamic acid residues (Glu) to -carboxyglutamic acid (Gla) on vitamin K-dependent protein. Vitamins are organic substances that function as regulators in the body. Biochemical functions: Vitamin D has three different sites of action i.e. Vitamin K1 and K2 are fat-soluble compounds. It also strengthens the teeth from the root and prevents loss or decay. The basis of this hypothesis is that the delivery of vitamin K to bone is less efficient than to the liver, as evidenced in part by the fact that in healthy individuals, hepatic Gla coagulation proteins are fully -carboxylated, whereas bone Gla proteins such as osteocalcin are only partially -carboxylated. Osteocalcin is another protein that requires vitamin K to produce healthy bone tissue. It has a vital role in modifying the blood clotting factors, which get synthesized in the liver as inactive precursors. Vitamin K (from the Danish word koagulation) is required for the synthesis of several blood clotting factors, including prothrombin and factors VII, IX, and X.
