Dioxygen as a Terminal Oxidant and the Formation of Dioxygen,minal oxidant. In this chapter, we shall discuss how dioxygen can be activated, with special reference to the methods used in biology. However, we first wish to point out that the requirement for activation and certain other properties make dioxygen an ideal terminal oxidant for life processes.

Dioxygenases,atalyzes the aerobic oxidation of fatty acids, particularly linoleic acid, to the hydroperoxides. More specifically, lipoxygenase catalyzes the oxidation of .-1,4-pentadienes to the hydroperoxides of .- l,3-dienes (Figure 18–2).

The chemistry of these compounds is discussed in Chapter 2 in connection with the autoxidation of hydrocarbons. The dialkyl peroxides are discussed in this chapter.

Labeled dioxygen is not incorporated into the product of the oxidation. These enzymes contain either copper or flavins. The discussion that follows considers first the copper oxidases and then the flavin oxidases.
