Vitamin D and vitamin K have which of the following features in common?

Vitamins D and K are fat-soluble vitamins that are important for calcium metabolism. Vitamin D encourages the synthesis of vitamin K-dependent proteins, which rely on vitamin K for carboxylation to function properly.

What causes vitamin K to be activated?

Vitamin K quinol is the reduced form of vitamin K that is required for carboxylation. The numbering system for enzyme reactions is 1,2, and 3. A vitamin K-dependent carboxylase activity (reaction 1) drives the carboxylation reaction, which simultaneously transforms vitamin K quinol to vitamin K 2,3-epoxide.

Why is vitamin K so important in the clotting process?

Your blood would not clot if you didn’t take vitamin K. The mechanism is complicated, but in general, vitamin K acts as a catalyst, converting some anticlotting proteins that are always present into clotting proteins when the body suffers a cut or wound.

What is nutritional K insufficiency, and how does it affect you?

Vitamin K insufficiency causes prothrombin and other vitamin K–dependent coagulation factors to be depleted, resulting in faulty coagulation and, potentially, bleeding. Vitamin K insufficiency is a leading cause of newborn mortality and morbidity around the world. Hemorrhagic illness of the infant is caused by a vitamin K deficiency.

What are the different types of vitamin K functional groups?
