A chemical group or radical related to alloxan; used in organic chemistry to describe certain structural features.
From 'alloxan' with the suffix '-oxy' (from Greek 'oxys' meaning 'sharp' or 'acid'), which is used in chemistry to indicate the presence of oxygen in a compound structure.
The 'oxy-' prefix appears in thousands of chemical terms, from 'oxygen' itself to 'peroxide' and 'hydroxide'—it's one of chemistry's most useful building blocks, but 'alloxy' specifically remains rare and technical, used mainly by specialist organic chemists.
