Imported from microbedecoder via ols-label-exact-chebi. source_id=kgmicrobe.trait:aspartate;
Re-grounded CHEBI:132943 -> CHEBI:29995. CHEBI:132943 is the charge-agnostic parent whose children are aspartate(2-) and aspartate(1-), so a bare label sitting on it declines to state a protonation state. The sibling record Glutamate — same amino-acid family, same bare-label form, same import — is on CHEBI:29987 glutamate(2-), and 30 other bare -ate labels in this corpus are likewise on charged terms. Both terms are stereo-agnostic, so no stereochemical claim is added; 'aspartate' is a ChEBI synonym of CHEBI:29995, so the lexical evidence survives. Counter-argument on record: MAPPING_SEMANTICS §3 step 4 would keep an evidence-free under-specified label on the parent, and Malate (same hierarchy shape) does exactly that — §3 does not address protonation, which #319 tracks.
