<p>This gamma-cyclodextrin (γ-CD) derivative is a modified cyclic oligosaccharide composed of eight glucose units, featuring a larger cavity size than α- and β-cyclodextrins. This structural characteristic allows γ-CDs to form inclusion complexes with a wider range of guest molecules, making it particularly versatile in various industries. In the food sector, it is used as a carrier and stabilizer for flavors, fat-soluble vitamins, and polyunsaturated fatty acids, protecting volatile compounds from evaporation. In pharmaceuticals, it enhances the solubility and bioavailability of poorly water-soluble drugs and, thanks to its larger ring size, allows for the encapsulation of larger molecules or even entire drug molecules. γ-CDs and derivatives are also used for environmental remediation and, in analytical chemistry, for the extraction and concentration of target substances.</p>

<p>Starch is an energy storing polysaccharide produced by higher plants and some algae. Pure starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol. It consists of two types of polysaccharide: the linear and helical amylose (α-1,4-linked glucose) and the branched amylopectin (α-1,4 and α-1,6-linked glucose). Depending on the plant, starch generally contains 20 to 25% amylose and 75 to 80% amylopectin by weight.</p>

<p>Dextran sulphate is a dextran derivative whose ulcer (colitis) -causing properties were first reported in hamsters and extrapolated a few years later to mice and rats. The exact mechanisms through which dextran sulphate induces intestinal inflammation are unclear but may be the result of direct damage of the monolayer of epithelial cells in the colon, leading to the crossing of intestinal contents (for e.g. commensal bacteria and their products) into underlying tissue and therefore induction of inflammation.  The dextran sulphate sodium induced ulceration model in laboratory animals has some advantages, when compared to other animal models of colitis, due to its simplicity and similarities to human inflammatory bowel disease.</p>
