Aa Hepatocytes Convert Nh3 Urea Toxic Liver Functions; Deamination

Front
Liver functions; Deamination of XS AA
Back
  • Hepatocytes synthesise most plasma proteins
  • Hepatocytes carry out transamination (conversion of an AA into another)
  • Deamination (removal of amine group from a molecule), proteins/AA cant be stored so hepatocytes deaminate AA and convert to NH3 then to urea in ornithine cycle to convert toxic NH3 to less toxic urea (excreted by kidneys), remainder of AA used in respiration or converted into lipids for storage
