what is the principal function of vitamin k in the human body?
232161
Vitamin K functions as a coenzyme for vitamin K-dependent carboxylase, an enzyme required for the synthesis of proteins involved in hemostasis (blood clotting) and bone metabolism, and other diverse physiological functions [3,5].

Vitamin K may help keep blood pressure lower by preventing mineralization, where minerals build up in the arteries. This enables the heart to pump blood freely through the body.

Rich in Vitamin K Amongst all the green leafy vegetables, across the board amaranth leaves have the highest quantity of vitamin K. This vitamin is needed for good bone health and also plays an important role in blood clotting. It promotes osteoblastic activity and strengthens bone mass.

Vitamins A, D, E, and K are fat-soluble vitamins, which means they need some fat to be absorbed. They are also stored in the fatty tissues in your body and the liver. Fat also helps protect your organs against trauma. Your body stores excess calories as fat, which is saved up as reserve energy.

Vitamin K at birth. Vitamin K helps the blood to clot and prevents serious bleeding. In newborns, vitamin K injections can prevent a now rare, but potentially fatal, bleeding disorder called 'vitamin K deficiency bleeding' (VKDB), also known as 'haemorrhagic disease of the newborn' (HDN).

Uses. Vitamin K is used to treat and prevent low levels of certain substances (blood clotting factors) that your body naturally produces. These substances help your blood to thicken and stop bleeding normally (e.g., after an accidental cut or injury).

It is also needed for healthy bones and other tissues. The effects of vitamin K toxicity can include jaundice in newborns, anemia due to rupture of red blood cells, and jaundice. (See also Overview of Vitamins.)

Originally identified for its role in the process of blood clot formation ("K" is derived from the German word "koagulation"), vitamin K is essential for the functioning of several proteins involved in physiological processes that encompass, but are not limited to, the regulation of blood clotting (coagulation) (1).

Summary of Role of Vitamin K in coagulation The vitamin K-related modification of the proteins allows them to bind calcium ions, which they cannot do otherwise. Without vitamin K, blood coagulation is seriously impaired, and uncontrolled bleeding occurs.

Vitamin K is a fat-soluble vitamin that makes proteins for healthy bones and normal blood clotting. According to the Harvard School of Public Health, vitamin K helps produce four of the 13 proteins needed for blood clotting. K also teams up with other vitamins.

Thiamin Function Thiamin, or vitamin B1, plays a major role in carbohydrate metabolism. Thiamin acts as a coenzyme along with phosphorus in important cellular reactions such as decarboxylation and transketolation.

The important functions of vitamin C include the formation of protein used to make skin, tendons, ligaments, and blood vessels for healing wounds and forming scar tissue, for repairing and maintaining cartilage, bones, and teeth and aid in the absorption of iron.

Vitamin K is a nutrient that the body needs to stay healthy. It's important for blood clotting and healthy bones and also has other functions in the body. If you are taking a blood thinner such as warfarin (Coumadin®), it's very important to get about the same amount of vitamin K each day.

Vitamin K is needed for blood clotting, which means it helps wounds heal properly. There's also some evidence vitamin K may help keep bones healthy.

Vitamin K is a group of compounds divided into two groups: vitamin K1 (phylloquinone) and vitamin K2 (menaquinone). Vitamin K1, the most common form of vitamin K, is mainly found in plant-sourced foods, especially dark, leafy green vegetables.

As a fat-soluble nutrient, vitamin E functions mainly as an antioxidant, which means it helps protect cells from damage caused by unstable molecules called free radicals.

Vitamin K is used to prevent and treat certain blood clotting (coagulation) issues. It's also used to prevent severe bleeding (hemorrhagic disease) in newborns. Vitamin K may be used in cases of ongoing IV feeding. It may also be used when antibiotics have killed bacteria in the intestines that make vitamin K.
