Root Explanation

Amphiphilic → It is formed from "amphi-" (meaning both or on both sides) and "philic" (from Greek "philia", meaning love or affinity). The word describes a molecule that has both hydrophilic (water-loving) and hydrophobic (water-fearing) parts, thus having an affinity for both water and fat.

Memory Tip

Think of 'amphi-' meaning 'both' and 'philic' meaning 'loving' — this helps you remember that amphiphilic molecules love both water and fat.
