A
  • carriersysteem transport xenobiotica & endogene stoffen naar gal
  • 2 eigenschappen > lipofilie & MW (conjugatie > toename > beter excretie
    > glucuronide & glutathionconjugaten goede substraten voot transporters
    > MW > 500 - gal
    > MW < 500 & > 300 - gal + urine
    > MW < 300 - urine
  • galvloeistof (0.5-0.8 ml/min)
