General description

Vitamin K2, also known as menaquinone, is a polyisoprenoid-substituted napthoquinone. Menaquinone-7 (MK-7) is a subtype of vitamin K2. It is found in animals, soy protein, fermented products and is primarily produced by bacteria.
Vitamin K2 (MK-7)-4′,5,6,7,8,8′-13C6 is a vitamin K2 isotope wherein C-4′, C-5, C-6, C-7, C-8, and C-8′ carbons are replaced by 13C6.

Application

Vitamin K2 (MK-7)-4′,5,6,7,8,8′-13C6 can be used as a stable isotope internal standard for data interpretation in specific biological samples.
