Trehalose is the major sugar in the hemolymph (blood) of many insects. Insects have open circulatory systems that bathe the tissues of the animal. For this reason, the fluid often contains high concentrations of trehalose (many times higher than glucose in closed circulatory systems). How does the type of disaccharide linkage (similar to sucrose in plants) prevent problematic reactions of the free aldehyde of the individual monosaccharides from occurring even when the disaccharide is at high concentrations in hemolymph
