Self-assembly in aqueous bile salt solutions

Impacts of feeding lipid supplements high in palmitic acid or stearic acid on performance of lactating dairy cows

“…Taurocholic has a pKa of 2.0 while glycocholic has a pKa of 3.9 (Setchell et al 2013) so taurine-conjugated bile acids should be more soluble at the lower duodenal pH of ruminants than glycine conjugates although Freeman (1984) states that conjugation of either glycine or taurine had little effect on solubilizing properties of bile salts. However, Madenci and Egelhaaf (2010) reported that critical micellar concentration was slightly larger for glycine conjugates than taurine conjugates. Smith and Lough (1976) reported that fully protonated long-chain FAs were poorly solubilized in sheep bile.…”

Study on Micelle Formation of Bile Salt Using Nuclear Magnetic Resonance Spectroscopy

“…5, the pair of 18 and 19 methyl groups can mutually interact with each other and induce aggregation. This antiparallel aggregation model with back-to-back faces has been discussed in previous reports 4,10,12,15,16 . Of course, aggregates or the basic units are not composed of only 2 molecules, but are contain a large number of bile salt molecules.…”

Supramolecular Organization of Magnesium Octa[(4’-benzo- 15-crown-5)oxy]phthalocyaninate in Aqueous Solutions of Polyelectrolytes and Surfactants: Analysis by Spectral Methods

“…As a result, mechanisms of self-organization, micelle shape and size are essentially different for SDC and common micelle-forming surfactants such as SDS (Figure 3). [18,19] The effect of additives on the absorbance of aqueous solutions of Mgcr 8 Pc is observed. When SDC is added to the Mgcr 8 Pc/PSS solution, a small increase of the Q-band absorbance at the field of the monomer is already observed.…”
