Trisaccharide

 

a carbohydrate consisting of three mono-saccharide residues linked by glycoside bonds. Trisaccharides may be of the reducing or nonreducing type; this, along with their monosaccharide content, determines their properties.

Most natural nonreducing trisaccharides are derivatives of the disaccharide sucrose, with residues of various types added to the glucose or fructose residue. The trisaccharides formed by addition of a glucose residue are gentianose and melezitose, respectively. Addition of a galactose residue produces raffinose (the most common trisaccharide) or planteóse, and addition of a fructose residue produces kestose. Reducing trisaccharides (panose and maltotriose) are relatively uncommon in nature.

(5) The dissected purified components of PGL-I, including the phenolic phthiocerol core, the mycocerosic acids, and deglycosylated PGL-I also showed no reactivity, indicating that the reactive component resided within the trisaccharide moiety.
The lowest sensitivity observed with ND-O-HSA ELISA may be due to the use of the synthetic disaccharide antigen, since the antigenic determinant of PGL-1is represented by the trisacchari determinal, and among the synthetic antigensthose that result in best reactivity with patient sera are those with di- (D-BSA) and trisaccharide (T-BSA) residues, which possess the non-reducing sugar 3, 6-dio-methyl B D-glycopyranoside.
