The molecular structures of different types of carrageenan. Carrageenans are large, highly flexible molecules that form curling helical structures. This gives them the ability to form a variety of different gels at room temperature. They are widely used in the food and other industries as thickening and stabilizing agents.

Differences in carrageenan chemistry, with Hypneaceae species producing kappa-carrageenan and Cystocloniaceae producing lambda-carrageenan, was another reason for their distinction. [5] However, these criteria were questioned and molecular analysis later showed that the two families had similar vegetative and reproductive characters.
Poligeenan is produced by the harsh acid degradation of carrageenan. Carrageenan in solution is processed at low pH (~1.0) and high temperature (90 °C (190 °F)) for up to six hours until the weight-average molecular weight (M w) has been reduced to the range 10,000 – 20,000 daltons (10–20 kDa).
