Root Explanation

Leukotriene → It is formed from "leuko-" (from Greek "leukos", meaning white) and "triene" (from Greek "tri-", meaning three, and "ene", a suffix used in chemistry to denote unsaturated hydrocarbons). The word refers to a class of compounds that are white blood cell derivatives with three double bonds in their structure.

Memory Tip

Think of 'white' ('leuko-') to remember that leukotrienes are related to white blood cells, and 'triene' indicates their chemical structure with three double bonds.
