Physical and Chemical Properties of vitamin K
Vitamin K 1 is a light yellow oil which crystallized at -20 ° and boils at 115-145 ° in a vacuum. This substance is soluble in chloroform, ethanol and other organic solvents. Its solution absorbs UV rays. Thus, in petroleum ether absorption maxima are at a wavelength equal to 243, 249, 261, 270 and 325 nm. In this series the greatest optical density ( = 420) Vitamin K shows at 249 nm.
Vitamin K 2 - yellow crystalline powder with a melting point 54 °, which dissolve in organic solvents. It has spectra similar to those of vitamin K 1, but less intensely absorbing UV rays. For example, in petroleum ether its absorption maximum is at 248 nm and is = 295.
Vitamin K 3 is a lemon-yellow crystalline substance with a characteristic odor. The melting point of 160 °. It is poorly soluble in water, due to lack of its long hydrocarbon molecule chains.
Daily requirement of vitamin K

HISTORY OF DISCOVERY OF VITAMIN K
In 1929, Danish scientist Henrik Dam (Henrik Dam) describe beriberi in chickens that were on the synthetic diet. The main feature of it was haemorrhage - bleeding in the subcutaneous tissue, muscle and other tissues. Add yeast as a source of vitamins B, and fish oil, rich in vitamin A and vitamin D, does not eliminate the pathological phenomena. It turned out that the healing effect with grain cereals and other plant products. Substances which cure hemorrhages, were named vitamin K, vitamin or coagulation, because it was found that bleeding in the experimental birds, for example, associated with decreased ability of blood to clot.
Edward Doyzi in 1936, tried to identify with stops plant opened in 1929, Danish biochemist Henrik Dame vitamin called it vitamin K (from the English «koagulations» - clotting). None of yarrow or with plantain then select the vitamin failed. As it turned out later, there was a small amount.
In 1939, the laboratory Carrera was first isolated from alfalfa vitamin K, was named filohinon. That same year, Binkley and Doyzi received from rotting fish meal with substance antyhemorahichnoyu action, but with other properties, the preparation isolated from alfalfa. This factor received the name of vitamin K 2 in contrast to the vitamin from alfalfa, called vitamin K 1.On top Doyzi synthesized artificial vitamin K 3 - medion.
