erythulose

ɪˈrɪθjuːloʊz

Definition

A naturally occurring keto-sugar, commonly found in red berries, which has recently been identified as a complex molecular component in interstellar space.

Etymology

The name is derived from 'erythrose,' a four-carbon sugar named after the Greek word 'erythros' meaning 'red,' combined with the chemical suffix '-ulose' used for ketose sugars. It reflects the compound's discovery in red berries and its specific chemical structure.
