Abstract: | The distribution of palmitate between the form bound by human serum albumin and the free form in plasma was calculated by use of 12 stepwise equilibrium constants and a computer program. Computations were carried out for molar ratios of palmitate to serum albumin of 0.5, 1,2,3, and 4. At most 0.0003% of the palmitate would be in the unbound form, and the remainder distributed among different complexes with albumin. At low molar ratios, the complexes with 1 to 2 moles of palmitate/albumin would predominate while at the highest ratio the complexes of 3 and 4 moles of palmitate/albumin would be most abundant. In the delivery of palmitate to tissues the relative contribution of the different complexes would change, as the molar ratio of fatty acid to albumin changed. |
