Figure 1 Synthesis and characterization of ACGC.jpg
Synthesis and characterization of an acryloylated, cholic acid-modified glycol chitosan (ACGC). (A) schematic of ACGC synthesis. (B) Representative proton NMR spectrum of ACGC with feeding molar ratio of cholic acid (CA) to glucosamine units of glycol chitosan (GC) being 0.18. Data were collected using a Bruker Avance Neo 500 MHz multinuclear NMR spectrometer and analyzed using the Bruker TopSpin 4.1.1 software.
