• CAS 2124-57-4 Menaquinone 7

  Vitamin K2 is a fat-soluble vitamin that has the ability to cross the blood-brain barrier (BBB) due to its lipophilic nature. All the existing forms of vitamin K2 consist of a common moiety in their chemical structure, which is a 2-methyl-1,4-naphthoquinone ring. This core chemical structure of vitamin K2 is called menadione. Each form differs from the others with respect to the degree of saturation and length of side chains. Menaquinone (also called MK-n) differs in the length of its side chain, varying from 4 to 15 isoprene units; n denotes the number of isoprene units present in the structure. The figure depicts the chemical structures of members of the vitamin K2 family. The differences in side chains of different forms give each of them a unique potency and absorption efficiency. Menaquinones with the absence of methyl group on naphthoquinone moiety at position 3 are called dimethyl-menaquinones and serve as precursors to menaquinone.
