Prevents Haemorrhages
vitamin K is a fat-soluble vitamin. It is essential for the production of a type of protein called prothrombin and other factors involved in the blood-clotting mechanism. Hence it is known as an anti-haemorrhagic vitamin.
Vitamin K exists in nature in two forms. Vitamin K1, originally isolated from lucerne (alfalfa), is the only form that occurs in plants. It is a yellow oil, soluble in fat solvents, but only slightly soluble in water. Vitamin K2 has been found to be produced by many bacteria. Vitamin K is not easily destroyed by light, heat, or exposure to air. It is, however, destroyed by strong acids, alkalis, and oxidising agents. X-ray and radiation, frozen foods, aspirin, air pollution, and mineral oil are other factors that can destroy vitamin K.
Functions in the Body
