Disulfide bond

A disulfide bond (or a 'sulfur-sulfur bond') is an electrical bond between two sulfur atoms. It's kind of like two pieces of metal that are stuck together and won't come apart. It's an important part of some molecules and makes them strong and stable. These strong bonds can be found in some proteins, like in our bodies, and some other molecules.
