Common Namevitamin k
DescriptionVitamin K1, also known as phytonadione or mephyton, belongs to the class of organic compounds known as vitamin k compounds. These are quinone lipids containing a methylated naphthoquinone ring structure, and vary in the aliphatic side chain attached at the 3-position. It is also required for the formation of anticoagulant factors protein C and S. It is commonly used to treat warfarin toxicity, and as an antidote for coumatetralyl. Vitamin K1 is an extremely weak basic (essentially neutral) compound (based on its pKa). In humans, vitamin K1 is involved in warfarin action pathway. Outside of the human body, Vitamin K1 is found, on average, in the highest concentration within a few different foods, such as highbush blueberries, common thymes, and common sages and in a lower concentration in hot chocolates, narrowleaf cattails, and napa cabbages. Vitamin K1 has also been detected, but not quantified in, several different foods, such as bamboo shoots, vanilla, green vegetables, american lobsters, and butter substitutes. This could make vitamin K1 a potential biomarker for the consumption of these foods. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. Use is typically recommended by mouth or injection under the skin. vitamin k is found in Homo sapiens, Prunus domestica and Secale cereale. vitamin k was first documented in 1982 (PMID: 7086539). Vitamin K is required for bone protein formation.
