Did You Know?

Luciferin got its name from the Latin word lucifer (meaning "light-bearing"), which is also a source of the word that is sometimes used as a name of the devil. We won't go into how Lucifer came to be called by that name-suffice it to say he wasn't always associated with darkness-but we will look a bit more closely at the Latin word lucifer. It comes from Latin luc-, meaning "light," plus -fer, meaning "bearing" or "producing." Additional relatives include the nontechnical adjective luciferous, meaning "bringing light or insight," and luciferase, the enzyme that catalyzes the oxidation of luciferin.
