Fructo-oligosaccharides (FOS), which are found in many vegetables, are short chains of fructose molecules. They differ from fructans such as inulin, which as polysaccharides have a much higher degree of polymerization than FOS and other oligosaccharides, but like inulin and other fructans, they are considered soluble dietary fibre. Using fructo-oligosaccharides (FOS) as fiber supplementations is shown to have an effect on glucose homeostasis quite similar to insulin.

WebIn the latter case, the two component monosaccharides are linked at their respective anomeric centers, and therefore, the carbonyl group is not available for reaction. Disaccharides are named as glycosides where the aglycone is another monosaccharide. Reducing disaccharides are named as substituted monosaccharides (Figure 10 ). Websubstituted saccharides, whose structures have recently been determined, appear to lack a suitable catalytic base located in an appropriate position. Soluble lytic trans-glycosylase [14], goose lysozyme [15], hevamine [16], and others fall into this category. Glycosyl hydrolases have developed various ways to lower
