quantitykind:AmountOfBiologicallyActiveSubstance
  a qudt:QuantityKind ;
  dcterms:description """"Amount of Biologically Active Substance" is the quantity of a substance expressed in
    International Units (IU), a measure of biological activity. It is dimensioned as mass (M) and organized under
    Mass Equivalent rather than as amount of substance (N): for any given substance one IU corresponds to a defined
    mass of an international reference preparation, so the quantity is a substance-dependent mass equivalent whose
    conversion factor is fixed per substance and resolved at the quantity level. It is deliberately not dimensioned
    as amount of substance, since one IU is not a fixed number of moles."""@en ;
