WGK 3
CAS No. 9001-00-7
EG-Nr. 232-572-4

Made from stems of young pineapple (Bromeliaceae).
Stock solution: 10 mg/ml in H2O. Unsoluble in organic solvents (acetone, ethanol, methanol etc.)

Highly active thiol proteinase (non-specific cystein protease), glycoprotein. Enzyme from Bromeliaceae, used in biochemistry and for meat tenderising. Preferable digestion at lysin, alanin, tyrosin and glycin. Degrades hemoglobin, gluten, collagen, globulin, casein and gelatin at pH 4-9. Cream-coloured, hygroscopic powder.
Bromelain is activated by cystein, bisufite salts, NaCN, Na2S, H2S and benzoate. The definite pH optimum depends on substrate and reaction parameters. pH stability of bromelain increases drastically after binding to the substrate.

Bromelain ~1200 GDU/g, for biochemistry

Highly active thiol proteinase (non-specific cystein protease), glycoprotein. Enzyme from Bromeliaceae, used in biochemistry and for meat tenderising.

Bromelain is activated by cystein, bisufite salts, NaCN, Na2S, H2S and benzoate. The definite pH optimum depends on substrate and reaction parameters. pH stability of bromelain increases drastically after binding to the substrate.


Unit-definitie

One GDU (gelatin digestion unit) will hydrolyse 1.0 mg of amino nitrogen from gelatin in 20 minutes at pH 4.5 at 45 °C. One bromelain tyrosine unit (BTU) corresponds to 1.1 GDU. 1200 GDU/g correspond to approx. 2.4 FIP-units/mg.


Gebruiksinstructies

Working concentration: substrate dependent.
pH working range: 4.0-8.0, pH optimum: 5-6, stabile at pH 3.0-6.5
Temperature optimum: 50-65 °C
Inhibitors: Hg2+, Ag+, Cu2+, antitrypsin, estatin, iodacetate, TLCK, TPCK, and temperatures of over 70 °C

Algemene informatie

Enzyme: a neoclassical, Greek artificial word ενζυμου, énzymon, derived from εν-, en- (in-) and ζυμη, zýmé (yeast, sourdough, archaic)
Ferments: comes from the Latin fermentum (ferments, sourdough)

There are six classes in which all enzymes are classified according to the particular reaction they catalyse:

Oxidoreductases (catalyse redox reactions)

Transferases (transfer functional groups among substrates)

Hydrolases (cleave bonds via addition of water)

Lyases/Synthases (cleave or synthesise complex products out of basic substrates without cleavage of ATP)

Isomerases (transform chemical isomers)

Ligases/Synthetases (cleave or synthesise complex products out of basic substrates via cleavage of ATP)


For reference substances

  • ROTICHROM® HPLC
  • ROTICHROM® TLC
  • ROTICHROM® GC
  • a batch-specific
      HPLC-chromatogram, TLC-chromatogram and GC-chromatogram respectively
    is prepared, which you can find in the respective certificate of analysis. The batch-related certificate of analysis with chromatogram is available online.
      Reference substances
  • ROTICHROM® CHR
  • are examined chromatographically. The respective chromatograms are not included in the certificate of analysis.
