Weitere Details:: IotaCarrageenin is a polysaccharide obtained from red algae. ι-Carrageenin has been used as a bioadhesive polymer to enhance the permeation effect of AT1002 on the nasal absortion of insulin. Iota-Carageenan is a gelling sulfated galactan extracted from red seaweed (typically Euchuma cottonii and Euchuma spinosum). 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. The α-linked galactose occurs as a 3,6-anhydro-2-sulphate unit and the β-linked sugar occurs as the 4-sulfate.
