Q:
D-Ser (CHEBI:29998) has a synonym D-Serine. It has no
parentage. D-Serine (CHEBI:16523) has as parents serine
and D-amino acids. My opinion is that these two
entities are one and should be combined, with the sum
of the parentage.
A: D-Ser (C3H5NO2) is an abbreviation for D-serine residue
in the sequence recommended by JCBN (IUPAC/IUBMB) and should
not be used for free D-serine (C3H7NO3). However the term
"D-serine" is used as a name for RESID:AA0195, that's why it
appears in synonyms. We plan to extend the ontology to
encompass more relationships (not only current IsA). Then
the relationships between the residues and free amino acids
will be explicitly stated.
