Figure 1From: Interactions of unconjugated bilirubin with vesicles, cyclodextrins and micelles: New modeling and the role of high pKa valuesFractions (f) of unbound monomeric UCB at various pH values. Calculated assuming high pKa values for UCB of 8.12 and 8.44 [4]. Abbreviations: H2B, UCB diacid; HB-, UCB monoanions; B=, UCB dianion. fH2B + fHB- + fB= = 1.Back to article page
