Sulfated polysaccharides carrageenan

Carrageenan. The term carrageenan [19000-07-1] is the generic description for a complex mixture of sulfated polysaccharides that are extracted from certain genera and species of the class Fhodophjceae red seaweed. 

The distribution of substituents and branches in polysaccharides may be random or uniform. Distributions are isotactic when the substituents are all on the same side of the main axis, syndiotactic when they alternate on either side, and atactic when they are located at random. Regularity in the first two tacticities is conducive to crystallization (Sperling, 1986). Positional isomerism can lead to dissimilar properties, e.g., sulfate in carrageenans influencing their ability to gel (Anderson et al., 1968 Guiseley et al., 1980).

Carrageenan, a broad generic class of sulfated polysaccharides derived from a wide range of seaweed species, can be classified as non-conventlonal fiber and is used in food as an emulsifier, stabilizer, thickener and gelling agent. 

Carrageenans " are a family of high molecular weight sulfated polysaccharides. The structures strongly depend on the source and conditions during extraction and purification process.
