NMR AND FTIR STUDY OF MOLECULAR DYNAMICS IN L-ALANINE / POLYETHYLENE GLYCOL COMPLEX Justyna Krzaczkowska, Zbigniew Fojud, Stefan Jurga Department of Macromolecular Physics, Adam Mickiewicz University, Poznań, Poland and Markus Antonietti Max-Planck Institute of Colloids and Interfaces, Research Campus Golm-Potsdam, Germany Study of conjugation process of complexes proteins with biocompatible polymers is very important with regard on pharmaceutical and biomedical application especially for drugs distribution. Polymer properly linked to amino acid modifies some of protein’s properties like molecular size, solubility but also protect them from enzymatic degradation [1]. Determination of the molecular dynamic of polymer chain and amino acid can yield information about site and way of binding polymer. Polyethylene Glycol (PEG) is widely used polymer in these field because of its outstanding physico-chemical properties: hydrophilicity, solubility in water and in organic solvents, non-toxicity, non-immunogenicity. In this paper we report proton NMR T 1 spin-lattice relaxation for L-Alanine / Polyethylene Glycol complex at 200 MHz using Bruker CXP 200 NMR spectrometer. The measurements performed in the temperature range from 100K to 285K allowed to determine an activation energy of the NH 3 group reorientation, E a = 5.16 kcal/mol (Fig.1). This value is lower then activation energy for pure L-Alanine, E a ≈ 8 kcal/mol [2]. Observed difference suggested that PEG are conjugated into L-Alanine structure probably by the amine group. 100000 10000 E a =5.16 kcal/mol T 1 [ms] 1000 100 2 4 6 8 10 12 1000/T [K] 001) 1907-1912 Fig.1.
