The wikipedia page is either too general to really explain anything, or too complicated (uses diagrams I've never seen before or don't know. Oxidative Modification of Lipids. Sign up using Triplet oxygen. Under low dioxygen concentrations, a family of protein transcription factors called hypoxia-inducible factor HIF become activated. In a recent study, Kujoth et al. The buildup of dioxygen in the air must have led to a great extinction of anaerobic organisms, since as we shall see, products of oxygen metabolism are very toxic. Allotropes of oxygen
