Vitamin K

Vitamin K is concerned within the carboxylation of glutamate residues in proteins and type gamma-carboxyglutamate residues and therefore wanted for these proteins which want this perform to be biologically lively. A few of them embody coagulation facotrs II (prothrombin), VII (proconvertin), IX (Christmas issue), X (Stuart issue), protein C, protein S and a growth-arrest-specific issue (Gas6). The first identified perform of vitamin K is within the regular clotting of blood, however it’s also useful in regular bone calcification. With out Vitamin K, carboxylation isn’t potential and therefore the proteins stay biologically inactive.

The vitamin can be wanted for bone metabolism in carboxylation of osteocalcin. Excessive serum concentrations of undercarboxylated osteocalcin and low serum concentrations of vitamin K are indicative of diminished bone mineral density. It additionally will increase the danger of hip fracture. Vitamin K prevents calcification of arteries in addition to different delicate tissues which is a consequence of growing older. It additionally has a task in upkeep of blood sugar degree. The pancreas has the second highest quantity of vitamin K within the physique.

The deficiency is uncommon and can happen on account of antibiotics, in newborns and attributable to impaired absorption.

Extra can be harmful and ends in hyperkalemia. An excessive amount of sodium within the weight-reduction plan can worsen the deficiency of potassium.

Older individuals have a better threat of deficiency associated signs as a result of impaired functioning of the kidneys and incapacity to excrete the mineral effectively.

2. The abbreviation for each is K though vitamin K doesn’t have any accepted acronym.

3. Greater doses ought to be prevented particularly with Potassium.

4. Vitamin K is principally concerned in blood clotting whereas Potassium discover many different physiological capabilities together with nervous system functioning.
