Biological process

menaquinone anabolism, menaquinone biosynthesis, menaquinone formation, menaquinone synthesis, menatetrenone biosynthesis, menatetrenone biosynthetic process, multiprenylmenaquinone biosynthesis, multiprenylmenaquinone biosynthetic process, vitamin K2 biosynthesis, vitamin K2 biosynthetic process

The chemical reactions and pathways resulting in the formation of any of the menaquinones. Structurally, menaquinones consist of a methylated naphthoquinone ring structure and side chains composed of a variable number of unsaturated isoprenoid residues. Menaquinones that have vitamin K activity and are known as vitamin K2.
