Key Takeaway Essential trace elements in mammals have four general roles: as macrominerals, as catalysts in group-transfer reactions or redox reactions, or as structural components. They can impair important biochemical systems, constituting an important threat for the health of plants and animal systems. Most of them are very important despite their low levels, and some don't seem to have much use at all (such as nickel, tin and vanadium). Though cobalt is understood to be an essential trace element in animal nutrition, the only detailed chemical knowledge of its biochemical action has to do with vitamin B12 and related.
