luciferin
- n pigment occurring in luminescent organisms (as fireflies); emits heatless light when undergoing oxidation
- In the presence of moisture luciferin oxidizes, forming oxy-luciferin, the substance which actually glows.
- He intends to detach their luminous posteriors and extract from them luciferina substance which fascinates many scientists.
- Many luminescent creatures secrete an easily oxidizable compound, luciferin, which is oxidized with the help of an enzyme, luciferase.
