Thanks to challenges involved in producing and safely containing the heavy element, few chemists have had the privilege of ...

Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

Hemoglobin, in turn, is made of smaller proteins known as heme, which contain an iron molecule that binds and transports the oxygen. “Our pathogens need iron for the same reasons,” Wander ...

The American Chemical Society, Lyon County Public Library and Murray State University recognized William Kelly's pneumatic process for refining iron as a National Historic Chemical Landmark on May 11, ...

Impossible has a special patent process for creating leghemoglobin (or heme), the iron molecule we associate with red meat’s taste. It makes the meat seem to bleed as it cooks and dramatically ...

DURING work with iron chelates, it was noted that many chemical analyses for total iron were inconsistent when repeated at intervals on solutions left standing on the laboratory bench in the light.

During the last 30 years, knowledge of iron-sulfur proteins has grown exponentially. Extensive investigation of this class of proteins has continually led to the discovery of new chemical ...
