Utilization of tyrosine‐containing dipeptides and N‐acetyl‐tyrosine in hepatic failure
Wilfred Druml, Wolfgang Hübl, Erich Roth, Herbert Lochs – 1 April 1995 – The impact of hepatic dysfunction on the elimination and hydrolysis of three potential tyrosine sources for total parenteral nutrition, the dipeptides L‐alanyl‐L‐tyrosine (Ala‐Tyr) and glycyl‐L‐tyrosine (Gly‐Tyr), and N‐acetyl‐L‐tyrosine (Nac‐Tyr) were evaluated in six patients with hepatic failure (five chronic, one acute) and seven healthy subjects. In controls, whole‐body clearance (Cltot) of Ala‐Tyr was higher than of Gly‐Tyr (3,169 ± 214 vs.
