What is the mechanism of action of vitamin K?
Vitamin K is the blood-clotting vitamin. The mechanism of action of vitamin K is discussed in terms of a new carbanion model that mimics the proton abstraction from the gamma position of protein-bound glutamate. This is the essential step leading to carboxylation and activation of the blood-clotting proteins.
How is vitamin K produced in the body?
