Surface Forms

threonine singular

threonines plural

Morphology

threonine = threon + ine

The element 'threon' is a technical combining form (not a standalone English word) and the suffix '-ine' is a specialised chemical ending, so the meaning is not derivable by an average B1 learner from familiar English morphemes.

Etymology

The word threonine comes from the sugar name threose and the related name threonic acid, because scientists first obtained this amino acid from that sugar. So the name stayed, and that's why threonine is the name for this essential amino acid you need in your diet.
