Diet with no vitamin k
Vitamin K is a group of structurally similar, fat-soluble vitamins the human body requires for complete synthesis of certain proteins that are prerequisites for blood coagulation that the body needs for controlling binding of calcium in bones and other tissues. A sample of phytomenadione for injection, also called phylloquinone. Click to discover in-depth, condition-specific articles written by our in-house team.

Low levels of vitamin K also weaken bones and promote calcification of arteries and other soft tissues. Tailored for the health areas that matter to you. The vitamin K-related modification of the proteins allows them to bind calcium ions, which they cannot do otherwise.

Please review the contents of the article and add the appropriate references if you can. Chemically, the vitamin K family comprises 2- methyl - 1,4-naphthoquinone (3-) derivatives. Animals may also convert it to vitamin K 2. (November 2015). An essential nutrient the body cannot produce enough of and which it needs to get from food. It is active as a vitamin in animals and performs the classic functions of vitamin K, including its activity in the production of blood-clotting proteins. In addition, bacteria typically lengthen the isoprenoid side chain of vitamin K 2 to produce a range of vitamin K 2 forms, most notably the MK-7 to MK-11 homologues of vitamin K 2. This article needs more medical references for verification or relies too heavily on primary sources. All forms of K 2 other than MK-4 can only be produced by bacteria, which use these forms in anaerobic respiration.
The most common number of these residues is four, since animal enzymes normally produce menaquinone-4 from plant phylloquinone.

Vitamin K 1, also known as phylloquinone, phytomenadione, or phytonadione, is synthesized by plants, and is found in highest amounts in green leafy vegetables because it is directly involved in photosynthesis.

If we do not take enough of these compounds, certain medical conditions can result. Unsourced or poorly sourced material may be challenged and removed. For example, vitamin C (ascorbic acid) is necessary for humans but not for dogs, because dogs can produce (synthesize) enough for their own needs, while humans cannot. We need to take vitamins from food because the human body either does not produce enough of them or none at all. Vitamins are organic compounds which are needed in small quantities to sustain life.
