Consideration has been given to the processes of conformational transition and aggregation in the aqueous solutions of ϰ-carrageenan depending on its concentration, the temperature of the system as a whole and the content of the potassium ions by the methods of polarimetry and spectroturbidimetry. It has been established that one and the same degree of mutarotation can be attained on variation of the concentration of both ϰ-carrageenan and potassium ions. The aggregation of the ϰ-carrageenan macromolecules occurs under the action of the potasssium ions and is independent of temperature.
