identifier: METPO:2000230
label: does not accumulate
definition: An OBJECT_PROPERTY asserting that an organism does NOT intracellularly
  accumulate a given chemical entity above environmental concentration. Negation companion
  of the positive 'accumulates' predicate. The intended use is predicate + class composition
  at assertion time, e.g. `<organism> <this property> <CHEBI class>`.

  changes: Deprecated generic transport or storage relation carrier; later replacement
    should use more specific trait records that combine the relation with the transported,
    imported, exported, accumulated, or sequestered entity, cellular location or compartment,
    and positive or negative context.
