For a time, the IFCC Expert Panel on Enzymes, contrary to the Expert Panel on Quantities and Units, suggested that the special term katal was against the international trend of restricting the number of special terms (17).
Thus, the outcome of this period was the general acceptance by the IFCC, IUPAC, and NB, as well as by the WHO (18,19) of a special term, katal (symbol, kat) for the SI-coherent derived unit "mole per second" when used with catalytic activity (symbol, z).
In addition, the katal is invariant of the measurement procedure, although the numerical value of a result depends on the procedure.
Flushed with the newly achieved international consensus, the IFCC, through the NPAC, proposed the special term and symbol, katal and kat, to the Consultative Committee for Units (CCU) of the International Committee for Weights and Measures (CIPM).
Hopkins renders the following line in Tamil, rich in alliteration--karkkontalai kanta katal
punamayil kan paniya--with an English line equally rich in alliteration and internal rhyme: "Sighing, she quivers with desire / then shrinks with shame; damp with sweat, / hair standing on end, her eyes fill with tears--." One hopes that Hopkins will eventually publish full translations of each of the poems analyzed here.
The yield of encapsulation for ADH and ALD was calculated as a proportion (in %) of the units of catalytic activity into loaded cells (in katals
, corrected for the volume of cells obtained) relative to the enzyme activity added to the RBC suspensions before hypoosmotic dialysis (in katals
, corrected for the volume of suspensions obtained).
