In a study designed to compare the efficacy of equimolar amounts of [K.sub.1] and MK-7, we measured the degree of osteocalcin carboxylation after a 6-week period of vitamin K intake.

Also on the gas exchanges, a significant influence of the phosphate fertilization was observed under the cowpea plants, so that the plants that received more phosphorus obtained higher rates of [CO.sub.2] assimilation, greater stomatal conductance and transpiration rates, and instantaneous efficiency of the carboxylation, independent of the salinity level studied (Figure 3A, B, C and D).

Vitamin K antagonists inhibit the recycling of vitamin K in the epoxide cycle, reduce carboxylation of coagulation factors, and cause calcifications in several arteries and valves [11].
Vitamin K is also a cofactor for carboxylation of glutamate to gamma carboxyglutamic acid (GLa).
Active vitamin K activates inactive coagulation factors (factor II, VII, XI, and X) through carboxylation. Moreover, S-warfarin inhibits vitamin K epoxide reductase (VKOR) 5 times more potently than R-warfarin.
