Study on conformational structure of tamarind seed polysaccharide and its sulfated derivative by light scattering method

Bui Ngo Tan, Quach Thi Minh Thu, Thanh Thi Thu Thuy

Abstract


The aim of this study was to study the conformational changing when sulfated groups were introduced to the molecular chain of native tamarind seed polysaccharide (TSP). Light Scattering (LS) method was used to determine conformation of TSP and its sulfated derivative TSPS. The results indicated that both TSP and TSPS have a highly branched and more sphere-like molecule; however, after sulfation, the TSPS became more branched structure than native polysaccharide.
