It is a protein circulating in the plasma essential to the clotting of blood. It is synthesized in the liver requiring vitamin K.
Prothrombin
It is any of a group of organic substances essential in small quantities to normal metabolism, found in minute amounts in natural foodstuffs, sometimes produced synthetically. They do not furnish energy, but are essential for energy transformation and regulation of metabolism
Vitamin
Who introduced the term vitamin?
Casimir Funk in 1912
The word came from the words?
vital and amine because it is an important substance to health and the first vitamin to be discovered belongs to a class of organic compounds known as amine (nitrogen containing)

Vitamin A, retinol
It is the natural form and is found only in animal sources like liver, or salt and freshwater fishes
