Viscous Solutions Reflect Long-Range Molecular Interactions
High viscosity in an aqueous solution is a sign of long-range molec- groups of sugar molecules. Solutions of DNA are highly viscous ular interactions, defined as interactions that extend through because isolated DNA fibers are extremely long (often in the mil-and connect many molecules. Concentrated sugar solutions limeter size range) and highly hydrated. As Szent-Gyorgyi dis-(molasses, for example) are viscous because of the extensive covered, the extensive aggregates formed by myosin and actin hydrogen-bonding networks established by the multiple hydroxyl also produce highly viscous solutions.
