Correlations between plasma albumin and tryptophan concentrations and tryptophan binding in humans and other species.
(A) Healthy human volunteers (n = 114) with mean albumin values of 49.6 g/l (range: 40.7-57.4). (B–E) correlations with 35 different animal species between albumin and the % free Trp (B), free Trp (C), total Trp (D) and bound Trp (E).
