In this study, we prepared amphiphilic polysiloxanes by introduction of hydrophobic and hydrophilic parts into a water-soluble poly(3-aminopropyl)siloxane. Fatty acid (lauroyl, myristoyl, palmitoyl, and stearoyl) chlorides and gluconolactone were employed as the reactants for the hydrophobic and hydrophilic parts, respectively. The reaction of the poly(3-aminopropyl)siloxane with fatty acid chlorides...
SummaryThis paper reports chemoenzymatic synthesis of amylose-grafted polyacetylenes according to the following reaction manners. Polymerization of a N-propargylamide monomer having a maltooligosacchairde chain was firstly carried out using a water-soluble Rh-catalyst in water, giving maltooligosaccharide-grafted polyacetylene. The 1H NMR spectrum of the product supported the structure of the desired...
The interaction between bovine serum albumin (BSA) and a hydrogel nanoparticle formed by the self-aggregation of cholesterol-bearing pullulan (CHP) was investigated by using an isothermal titration microcalorimeter. In water, one nanoparticle of the CHP self-aggregates strongly bound approximately one BSA molecule. The heats associated with the complexation were exothermic. The complexation is enthalpically,...
