Natural Product Identification
Common Namevitamin k2
DescriptionVitamin K2 belongs to the class of organic compounds known as sesterterpenoids. These are terpenes composed of five consecutive isoprene units. Thus, vitamin K2 is considered to be a quinone lipid molecule. Vitamin K2 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
