Immunostimulatory properties of coffee mannans.
30 Jul 2009
Coffee infusion mannans are acetylated polysaccharides containing single Galp and Araf residues as side chains of a beta-(1 --> 4)-Manp backbone. These mannans are structurally similar to the bioactive acetylated mannans from Aloe vera (AV). In this ... Read more...
