Sulfate groups position determines the ionic selectivity and syneresis properties of carrageenan systems

Carrageenan-Based Pickering Emulsion Gels Stabilized by Xanthan Gum/Lysozyme Nanoparticle: Microstructure, Rheological, and Texture Perspective

“…Carrageenan (kappa) as a linear polysaccharide is composed of D-galactose and 3, 6-dehydrated D-galactose with one sulfate groups per repeating disaccharide [ 20 ]. The kC solution (≥1%) can spontaneously form a gel at room temperature after heating at 70 °C for 20 min.…”

Modulating Ionic Linkages in the Heterocyclic Sulfated Polysaccharide Carrageenan for Enhanced Selectivity Against Amelanotic Melanoma Cells

“…The specific affinity to tumor cells makes carrageenan a matter of concern for the targeted delivery with active drug loading with a synergistic effect [10,11] . Carrageenan has a sulfate group with the cations, which plays a very important role in the physicochemical properties, mostly carrageenan found with potassium ions [12,13] …”

“…[10,11] Carrageenan has a sulfate group with the cations, which plays a very important role in the physicochemical properties, mostly carrageenan found with potassium ions. [12,13] The gelling property and hydrophilicity are highly dependent on the ion present, [14] as it is well established that iota carrageenan gives better gel with Ca 2 + [15] and kappa carrageenan gives with K + . [16] The galactose-based heterocycle possesses various biological concerns, but the binding of the core to tumor cells is found to be an area of concern.…”
