What is the function of luciferin? luciferin, in biochemistry, any of several organic compounds whose oxidation in the presence of the enzyme luciferase produces light. Luciferins vary in chemical structure; the luciferin of luminescent bacteria, for example, is completely different from that of fireflies.
Why is it called luciferin? “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.
How many Luciferins are there? There are five basic luciferin–luciferase systems (Table 8.3).
How does luciferin glow? Bioluminescence is light produced by a chemical process within a living organism. The glow occurs when a substance called luciferin reacts with oxygen. This releases energy, and light is emitted. An enzyme called luciferase facilitates the reaction.
