CHEBI:61265 β-D-glucopyranosyloxymethyluracil residue contains the following definition: "A deoxyribonucleotide residue in which a 5-hydroxymethyluracil residue is glycosidically linked via the 5-hydroxymethyl oxygen to β-D-glucose."
However, its ontology only contains a single tree, stating that this entry
is a CHEBI:55367 deoxyribonucleotide residue.
I would suggest that the following relationship be added:
Outgoing:
has functional parent CHEBI:16964 5-hydroxymethyluracil (which has functional parent CHEBI:17568 uracil).
