| Etymology | "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. |
| Examples | "Luciferins vary in chemical structure; the luciferin of luminescent bacteria, for example, is completely different from that of fireflies." - From an article at Encyclopædia Britannica Online, 2012 "Light is produced by fireflies through a chemical reaction between luciferin and its enzyme counterpart, luciferase." - From an article at photonics.com, June 20, 2012 |
| Definition | : any of various organic substances in luminescent organisms (as fireflies) that upon oxidation produce a virtually heatless light |
