abstract = {Possible denaturation or tertiary structural changes of the
protein human serum albumin (HSA) upon adsorption of uremic
toxin is investigated using small-angle neutron scattering
(SANS). Calorimetric data in previous studies give proof of
the binding between HSA and two classes of uremic toxins: i)
small molecular weight and ii) middle molecular weight
molecules. A representative polyelectrolyte of negative net
charge is used as a model middle molecule and two molecules
phenylacetic acid (PhAA) and indoxyl sulfate (IDS) represent
the small molecular weight toxins. The present study find no
proof of destabilization of the protein structure upon toxin
uptake. Analyzing the structure factor of scattering
intensities from high concentrated protein samples complexed
with PhAA and IDS show that interaction between native and
complexed HSA is also not altered. However, a small effect
of the net charge of HSA is found in the case of urea
modified proteins},
