| Mutant M249 preferentially accumulated menaquinone, which contains tetrahydrogeranylgeraniol as its side chain. |
| The most common form of vitamin K in animals is menaquinone 4, produced by intestinal bacteria from exogenous naphthoquinones and transformed endogenously in our own cells. |
| The most common form of vitamin K2 in animals is menaquinone 4, produced by the processing of exogenous and bacterial naphthoquinones. |
| When taken together, menaquinone 7 and vitamin D3 act synergistically, significantly boosting their efficacy. |
| When administered, vitamin K 3 is alkylated to one of the vitamin K 2 forms of menaquinone. |
| The number of isoprene residues, where 1 isoprene unit consists of 5 carbons comprising the side chain, is used to characterise the menaquinone homologues. |
