CONFORMATIONAL COMPARISON BETWEEN PURE AND CHEMICALLY MODIFIED AGAROSE
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 1
Abstract
In this work, we conduct a statistical study to compare the molecular conformations of pure agarose and agarose chem-ically modified. . It is to follow the process of their gelation through calculation of the rate of helix according to the tem-perature. Indeed, it is shown that the conformation of the helix is marked in the pur agarose gel by comparison with aga-rose chemically modified at the same temperature. It followed from there a study of the thermal hysteresis which confirms the reversibility of the two types of gel. Finally, we analyzed the addition of some organic compounds as co-solvents to understand their influence on the formation of the gel corresponding to the chemically modified agarose.
