Introduction

Vitamin K2, the main storage form in animals, has several subtypes, which differ in isoprenoid chain length. These vitamin K2 homologues are called menaquinones, and are characterized by the number of isoprenoid residues in their side chains. Menaquinones are abbreviated MK-n, where M stands for menaquinone, the K stands for vitamin K, and the n represents the number of isoprenoid side chain residues. For example, menaquinone-7 (abbreviated MK-7) has seven isoprene residues in its side chain. For this product,vitamin K2 is present as all-trans MK-7 in soyabean oil.
