Agars and carrageenans are 1,3-α-1,4-β-galactans from the cell walls of red algae, substituted by zero (agarose), one (κ-), two (ι-), or three (λ-carrageenan) sulfate groups per disaccharidic monomer. Agars, κ-, and ι-carrageenans auto-associate into crystalline fibers and are well known for their gelling properties, used in a variety of laboratory and industrial applications. These sulfated galactans constitute a crucial carbon source for a number of marine bacteria. These microorganisms… CONTINUE READING
