2-thiouracil and its chemically related active substances have a sulfur atom, which gives the molecules its unusual, medically relevant properties. "Another special feature is that these molecules ...

Iron is an element. It is made of only one type of atom: iron atoms. Sulfur is another element. It contains only sulfur atoms, and nothing else, so it is pure. When we mix two different pure ...
