Vitamin K is a family of structurally similar, fat-soluble vitamers found in foods and marketed as dietary supplements. [1] The human body requires vitamin K for post-synthesis modification of certain proteins that are required for blood coagulation ("K" from Danish koagulation, for "coagulation") or for controlling binding of calcium in bones and other tissues. [2]
Menadione is a synthetic [3] [4] organic compound with the formula C 6 H 4 (CO) 2 C 2 H(CH 3). It is an analog of 1,4-naphthoquinone with a methyl group in the 2-position. [5] It is sometimes called vitamin K 3. Use is allowed as a nutritional supplement in animal feed because of its vitamin K activity.
Phytomenadione, also known as vitamin K 1 or phylloquinone, is a vitamin found in food and used as a dietary supplement. [4] [5] It is on the World Health Organization's List of Essential Medicines. [6] It is used to treat certain bleeding disorders, [5] including warfarin overdose, vitamin K deficiency, and obstructive jaundice. [5]
"Vitamin K supports the synthesis of osteocalcin, a protein that binds calcium in bones, enhancing bone mineralization and reducing fracture risk," Dr. Durham says. "This is vital for helping to ...
General structure of vitamin K 2 (MK-n) Vitamin K 2 or menaquinone (MK) (/ ˌ m ɛ n ə ˈ k w ɪ n oʊ n /) is one of three types of vitamin K, the other two being vitamin K 1 (phylloquinone) and K 3 . K 2 is both a tissue and bacterial product (derived from vitamin K 1 in both cases) and is usually found in animal products or fermented foods. [1]
Naphthoquinone forms the central chemical structure of many natural compounds, most notably the K vitamins. 2-Methyl-1,4-naphthoquinone, called menadione, is a more effective coagulant than vitamin K. Other natural naphthoquinones include juglone, plumbagin, droserone. Naphthoquinone derivatives have significant pharmacological properties.
“Vitamin K is a fat-soluble vitamin, so your body stores it in fat tissue and the liver,” Heather Viola, DO, Primary Care Physician at Mount Sinai Doctors-Ansonia, tells Fortune.
