Iron-Sulfur Cluster - an overview ScienceDirect Topics

Iron–sulfur clusters self-assemble in aqueous solutions under anaerobic (oxygen-free) conditions in presence of iron and sulfide ions along with a thiol-containing reductant. If an apoprotein with an iron–sulfur cluster-binding site is added to the solution, the clusters self-insert into the site via a thiol exchange mechanism.

The Sulfur Solution — NaturoDoc

Dec 16, 2019 Sulfur is also a common ingredient in homeopathic remedies, developed in the 19th century and still popular today as over-the-counter remedies. In the 1920s, “colloidal sulfur” was used to treat arthritics. Now, researchers understand that sulfur forms part of the matrix of bone joints in the form of chondroitin sulfate and glucosamine sulfate.

Iron Sulfide - an overview ScienceDirect Topics

The sulfur electrode was replaced with transition metal sulfides, such as iron sulfides (FeS x) and cobalt sulfide. Iron disulfide (FeS 2) is an attractive choice in electrodes because it is an abundant mineral (pyrite), and hence, most development centered on using pyrite from mines around the world with appropriate crushing and purification ...
