Figure 1From: Purification of DP 6 to 8 chitooligosaccharides by nanofiltration from the prepared chitooligosaccharides syrupMolecular structures of glucosamine and DP 3 chitooligosaccharide. Structurally, chitooligosaccharides, including glucosamine and trimer, are linear oligosaccharides composed of 2-amino-2-deoxy-D-glucopyranose and 2-acetamino-2-deoxy-D-glucopyranose units which are linked by β(1 → 4) glycosidic bonds. (A) The molecular structure of glucosamine. (B) The molecular structure of DP 3 chitooligosaccharide.Back to article page
