The number n of isoprenyl units in their side chain differs and ranges from 4 to 13, hence vitamin K 2 consists of various forms. [2] It is indicated as a suffix (-n), e. g. MK-7 or MK-9. The most common in the human diet is the short-chain, water-soluble menatetrenone (MK-4), which is usually produced by tissue and/or bacterial conversion of ...
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.

Food storage in refrigerators may not be safe unless there is close adherence to temperature guidelines. In general the temperature should be maintained at 4 °C (39 °F) or below but never below 1 °C (34 °F). [8] Safe storage times vary from food to food and may depend on how the food has been treated prior to being placed in the refrigerator.
And then there's vitamin K2, which is found in meat, dairy and eggs. Its benefits include boosting bone density, cardiovascular and dental health, and also helping to regulate blood clotting.
MK-4 is the major form of Vitamin K in vertebrate animals, including humans and common forms of meat animals. It is produced via conversion of vitamin K 1 in the body, specifically in the testes, pancreas and arterial walls. [2] The conversion is not dependent on gut bacteria, occurring in germ-free rats [3] [4] and in parenterally-administered ...
Powdered potassium sulfide anhydrous. Potassium sulfide is an inorganic compound with the formula K 2 S.The colourless solid is rarely encountered, because it reacts readily with water, a reaction that affords potassium hydrosulfide (KSH) and potassium hydroxide (KOH).
The Coolgardie safe is a low-tech food storage unit, using evaporative cooling to prolong the life of whatever edibles are kept in it. It applies the basic principle of heat transfer which occurs during evaporation of water (see latent heat and heat of evaporation).
A meat absorbent pad or meat pad, colloquially known in North America as a meat diaper, refers to the absorbent pad found in pre-packaged (or case-ready) meats. Its purpose is to absorb the juices released from the meat during storage and transportation, helping maintain the meat's appearance and reduce spoilage . [ 1 ]
