Morphology

ketotetrose = tetrose (transparent) = keto + tetrose

Formed by productive chemical combining form 'keto-' (ketone) plus the established term 'tetrose' (four-carbon sugar), so the meaning is directly compositional.

Etymology

Ketotetrose breaks into keto- and -tetrose, where keto- comes from ketone, a common chemistry word meaning 'a chemical group' and -tetrose comes from tetra meaning 'four'. So a ketotetrose is a sugar with a 'keto' group and 'four' carbon atoms.
