Vitamin K2 is a series of terpene side chain compounds containing 2-methyl-1, 4-naphthoquinone parent nuclei and different numbers of isoprene structural units at C3 position. According to the number of carbon elements on the terpene side chain, vitamin K2 can be divided into K2(10), K2(20), K2(35), K2(40), etc. Vitamin K2 is a fat-soluble vitamin, a derivative of naphthoquinone group of phylloquinone biological activity, and is one of the indispensable important vitamins in the human body. Vitamin K2(35) is a terpene side chain with 35 carbon elements of vitamin K2; Vitamin K2(35) is also known as menadione-7, named after the seven isoprene side chains in its terpene side chain. Vitamin K2 is the only biologically active form of vitamin K and is used to accelerate blood coagulation, maintain clotting time, and treat bleeding caused by vitamin K deficiency.
