Root Explanation

Menadione is derived from 'mena-' (from the Greek 'mene', meaning moon) and 'dione' (from the Greek 'dion', meaning divine). The term refers to a synthetic form of vitamin K, which is associated with the moon due to its historical connection with blood coagulation and the cycles of nature.

Memory Tip

Think of the 'moon' ('mena-') and its 'divine' ('dione') qualities, which helps you remember that menadione is a synthetic form of vitamin K, often linked to natural cycles.
