Conformational changes in the bilirubin-human serum albumin complex at extreme alkaline pH.

Light-absorption, c.d. and fluorescence of the bilirubin-albumin complex were investigated at extreme alkaline pH. Above pH 11.1 albumin binds the bilirubin molecule, twisted oppositely to the configuration at more neutral pH. On the basis of light-absorption it is shown that two alkaline transitions occur. The first alkaline transition takes place at pH between 11.3 and 11.8, co-operatively di...

Electrophoretic Behavior of Normal Human Serum Albumin at pH 4.0

In the preceding paper on the behavior of pooled normal human serum albumin in various buffers at pH 4.0 (1)) it was demonstrated that the electrophoretic pattern of albumin shows a single moving boundary in the presence of the lower fatty acids, excepting formic and acetic acid, and of certain diand tribasic organic acids. This phenomenon is probably a consequence of the interaction between th...

Depression of serum alkaline phosphatase activity by human serum albumin.

The daily intravenous administration of 50 gm. of concentrated saltpoor human serum albumin’ produces a rise in serum albumin level and a decline in urinary calcium and phosphorus excretion (1). These latter changes have been interpreted as evidence for an albumin-induced stimulation of osteogenesis (2). The consistent finding of a concomitant depression of serum alkaline phosphatase activity w...

Interaction of bilirubin with human serum albumin and cationic detergents.

In biological systems, once the unconjugated bili­ rubin is released into the plasma, it is transported rather firmly bound to albumin1_3. The binding equilibria of bilirubin to albumin and tissues are of great interest in order to be able to understand the development of hyperbilirubinemia3. It is well established that while the first mole of bilirubin is tightly bound to albumin, the subseque...

The relationship between anthropometry and serum concentrations of alkaline phosphatase isoenzymes, liver-enzymes, albumin, and bilirubin.

Alkaline phosphatase (ALP) is present in human preadipocytes. The aim of this study was to determine the relationship between anthropometry and serum levels of ALP isoenzymes, liver enzymes, albumin, and bilirubin. Anthropometric variables; serum total, bone, liver, and intestinal ALP levels; and alanine aminotransferase (ALT), albumin, total protein, total bilirubin, and g-glutamyltransferase ...
