Morphology

DEAE + cellulose

DEAE is a technical abbreviation (diethylaminoethyl) not a common lexical item and is listed here as '[Word not found in dictionary]', so a B1 learner who only knows the common word 'cellulose' could not infer the chemical modification or functional role. The term is domain-specific jargon describing a chemically modified cellulose used as an ion-exchange medium, so its meaning is not derivable from ordinary constituent knowledge and is therefore opaque to general learners.

Etymology

The name DEAE cellulose shows that ordinary cellulose, a plant fiber, has a chemical called DEAE attached. Think of the fibers as tiny beads with small positive 'hooks' from DEAE that grab negatively charged molecules. That's why this material is used in labs to 'catch' and 'separate' molecules.
