l-Carrageenan

Lambda-Carrageenan is a non-gelling sulfated galactan extracted from red seaweed (typically Gigartina stellata and Chondrus crispus). The structure of all carrageenans consists of a strictly alternating masked repeating unit of 1,3-linked α-D-galactose and 1,4-linked β-D-galactose. λ-Carrageenan has the α-linked unit 2-6-disulphated and the β-linked unit is 2-sulfated. λ-Carrageenan is a seaweed polysaccharide, it is a potent antitumor agent. λ-Carrageenan has been generally used as proinflammatory agent in the basic research.||Synonyms:|lambda-Carrageenan; (3-((4,5-dihydroxy-6-(hydroxymethyl)-3-(sulfonatooxy)tetrahydro-2H-pyran-2-yl)oxy)-4,6-dihydroxy-5-(sulfonatooxy)tetrahydro-2H-pyran-2-yl)methyl sulfate||CAS No:|9064-57-7||Molecular Formula:|NA||Molecular Weight:|NA||Appearance:|White to light yellow or light brown powder||Purity:|As reported||Loss on Drying:|≤15%||Solubility:|Water: 10mg/ml||Storage and Stability:|May be stored at RT for short-term only.
