What it does, reaction by reaction
1 reactions
Heme Degradation (Bilirubin Pathway) Amino Acid & Nitrogen Metabolism · Reticuloendothelial system, liver ER, gut
step 3
Irreversible/directional
Unconjugated bilirubin (albumin-bound) → hepatocyte-associated unconjugated bilirubin
Converts Unconjugated bilirubin into Hepatocyte-associated unconjugated bilirubin
› Notes
Hepatic sinusoidal uptake is carrier-mediated (not a covalent enzymatic conversion), followed by cytosolic binding to ligandin/GST proteins. Albumin-bound bilirubin cannot be filtered by the kidney and is not directly excreted in urine.
