Carrageenan Iota Type

CAS number 9062-07-1

Carrageenan is a naturally-occurring family of polysaccharides extracted from red seaweed. Upon cooling and in the presence of appropriate cations, (K+, Ca2+), carrageenan polymers align themselves to form double helices. Iota carrageenan binds water and forms dry, elastic gels in the presence of calcium salts. Ca2+ ions make bonds between the carrageenan -molecules to form helices. The negative charges associated with the 2-sulphate groups on the iota carrageenan molecules do not allow the helices to aggregate to the same extent as Kappa carrageenan.
