The liver can metabolise ammonia (NH3) via three pathways The degree to which each pathway is used depends upon pH and the need for bicarbonate to be preserved or produced: Urea Production(Ureagenesis) Glutamine Production Upstream hepatocytes convert ammonia to urea...
Can be metabolised via two mechanisms: Oxidation to water and CO2 (70% in health) Gluconeogenesis (30% in health) Both mechanisms consume a Hydrogen ion (H+) and thus have an alkalinising effect Mechanisms can be used to clear acid in critical illness: Infusion of...
1 Location Predominantly occurs in the distal convoluted tubules Process Glutamine is converted by tubular cells to form ammonia ( NH3) and glutamic acidAmmonia diffuses into the tubular lumen and combines with H+ to form ammonium ions (NH4+)Can accompany negatively...
