Computer simulation of an amylosic chain conformation, which consists of conformational energy analyses, Monte Carlo studies and applications of helical wormlike chain theory of Yamakawa, was carried out. The graphic representation obtained showed a deformed helix conformation of the amylosic chain.
The micro-Brownian motion of the amylosic chain was measured by the fluorescence method, through which the mode of helix-coil transitions of the chain due to temperature and pH changes were illustrated.
The ability of complex formation of amylose with organic compounds in an aqueous solution was investigated. The heterogeneous complex formation between the solid helical amylose and vapor of organic compounds was also investigated by means of inverse gas-chromatography. From the results it was concluded that the dipolar cooperative force acting between the amylose helix and the polar compound may be one of the important forces responsible for the complex formation as well as the hydrophobic effect.
