摘要: The conformation response of calf thymus DNA and β-lactoglobulin (BLG) to solvent conditions altered by varying amounts ethanol (EtOH) tert-butanol (TBA) has been monitored viscosimetry circular dichroism measurements. A correlation between the effects EtOH TBA on condensation BLG denaturation clearly appears from data, suggesting that a similar molecular mechanism is responsible for alcohol these two very different systems processes. These alcohol-induced transitions appear in concentration range (alcohol mole fraction X = 0.22 0.07 TBA, respectively) where changes association state molecule occur (see compressibility IR data).
