摘要:
Vitamin K in its hydroquinone form, vitamin KH2, is transformed to vitamin K oxide concurrent with the abstraction of the gamma-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. (C) 1998 Elsevier Science Ltd.
