Tips

usage
朊 is an older single-character word for protein; modern Chinese normally says 蛋白质. It survives in the technical term 朊病毒 (prion, the misfolded protein behind mad cow disease).

Components

radical
⺼ ròu
meat; flesh
The meat-flesh radical ⺼ (not the moon 月) marks this as a body/biological-tissue word, appropriate for protein, the building block of flesh.
phonetic
元 yuán
origin; basic unit
元 supplies the sound (shifted from yuán to ruǎn); its 'basic unit' sense loosely suits protein as a fundamental building block.
