Mechanism of oxygenation of naphthoquinone derivative

Ham, Seung Wook,Lee, Geun-Hyung

, p. 4087 - 4090 (1998)

Vitamin K in its hydroquinone form, vitamin KH2, is transformed to vitamin K oxide concurrent with the abstraction of the γ-hydrogen of Glu leading to Gla. The nonenzymatic model supports that oxygenation of the monoanion of vitamin KH2 can produce the peroxy anion at the 4-position yielding vitamin K oxide.
