The effects of the novel bifidogenic trisaccharide
, neokestose, on the human colonia microbiota.
18) Both di- and trisaccharide
parts of the molecule are principal antigenic determinants of PGL-I.
Honeydew honey is characterized by a higher concentration of oligosaccharides, mainly trisaccharides
melezitose and raffinose, which usually are not found in blossom honeys [7,8].
However as a ligand very few carbohydrate moieties have receptor binding avidity and few carbohydrates are biologically active in the Di and Trisaccharide
form (For recent detailed review Leung et.

In the early definition of CDT, the sum of the asialo-, monosialo-, and disialotransferrin isoforms was called "carbohydrate-deficient transferrin' because in alcoholics, some of the serum transferrin (Tf) molecules apparently lacked two to four of their terminal trisaccharides
Included are sugars such as glucose and other monosaccharides, sucrose and other disaccharides and other slightly more complex sugars, trisaccharides
However, most carbohydrates are hydrolyzed into trisaccharides
and disaccharides in the duodenum and jejunum, where they undergo further hydrolysis into monosaccharides.
were released from the non-reducing terminus, and then transferred to the non-reducing terminus of other oligosaccharides (Fig.
Assays that detect PGL-I antibodies can utilise the native glycolipid, synthetic PGL-I di- or trisaccharides
coupled to bovine or human serum albumin and a variety of neoglyco conjugates with up to 40 to 50 residues per molecule, with a sensitivity higher than that of the native PGL-I antigen.
14]C-sucrose was incorporated into a trisaccharides
group, but these do not contain an alditol component (BOGO, 2001).
These stevia sweeteners are similar in structure in that a steviol aglycone is connected at C-4 and C-13 to mono-, di- or trisaccharides
consisting of glucose and/or rhamnose residues, as shown in Figure 1.
