What's the difference between hyperoxide and oxide?

Hyperoxide


Definition:

  • (n.) A compound having a relatively large percentage of oxygen; a peroxide.

  • (17) The reducing power loss and the excretion of glutathione disulfide are thought to be consequences of a hyperoxidant state; the adhesion of hyphae is thought to be a response to the hyperoxidant state.
  • (18) Although the cause of neuronal death in Parkinson's disease remains unknown, a hyperoxidation phenomenon has been implicated as a potential cytotoxic mechanism.
  • (19) However, this reoxidation of NADH was only partial in the mild and moderate groups, and a pronounced hyperoxidation occurred in the severe group.

Oxide


Definition:

  • (n.) A binary compound of oxygen with an atom or radical, or a compound which is regarded as binary; as, iron oxide, ethyl oxide, nitrogen oxide, etc.

Example Sentences:

  • (8) Peripheral blood monocytes undergo an oxidative burst similar to that seen in neutrophils.
