Product Information

• Name: lambda-Carrageenan
• Brand: Biosynth
• Description: Lambda-Carrageenan is a non-gelling sulphated 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-sulphated.; The image was kindly provided by Prof Mike Guiry from Cork who runs ‘The Seaweed Site’.
