Morphology

protein + molecule

The meaning "a molecule that is a protein" is directly and transparently derived from combining 'protein' (a type of biological compound) with 'molecule' (a smallest bonded atomic unit). This straightforward noun–noun composition is a regular, cross-linguistically common pattern, so a B1 learner who knows both constituents will readily understand the phrase.

Etymology

Protein molecule comes from the Greek word 'protos' meaning 'first' and the word molecule which means a very small piece. Scientists called protein this way because they saw these substances as the first or main 'building parts' of living things, and molecule shows they are tiny. That's why protein molecule means 'a small, important part of cells'.
