HEMATIN COMPOUNDS IN PHOTOSYNTHETIC BACTERIA

Unsaturated lipide oxidation catalyzed by hematin compounds.

Hematin catalysis of unsaturated lipide oxidation is probably a primary reaction in many types of pathological unsaturated fat oxidation in viva (l-3) and in the spoilage of frozen meat products by oxidative fat rancidity (4). Some of the properties of hematin catalysis have been described (4-8), but knowledge of the reaction mechanism and the reaction products is relatively meager. The catalyt...
