IPA: //ˈiːkwərɪn//
KK: /ˈiːkwərɪn/
A type of protein found in some jellyfish that glows in the dark when it comes into contact with calcium ions.
Researchers studied aequorin to understand its role in bioluminescence in jellyfish.
**Aequorin** → The word 'aequorin' is derived from the Latin 'aequor' (meaning sea or level surface) and the suffix '-in' (commonly used in chemistry to denote substances). Aequorin is a protein originally found in the jellyfish, which emits light in the presence of calcium ions, thus relating to its marine origin.
Think of 'aequor' meaning sea, and remember that 'aequorin' is a substance found in jellyfish from the sea that glows.
