Any of a class of sugars whose molecules contain two monosaccharide residues.
- ‘Several physiologically important disaccharides are sucrose, lactose and maltose.’
- ‘Among them, the most effective in preserving a more native-like structure are the disaccharides sucrose and trehalose in dry films and the polymer dextran in wet films.’
- ‘The same trend is observed for the mono- and the disaccharide with a more pronounced swelling excess with the disaccharide, as previously reported with other disaccharides like lactose or saccharose.’
- ‘Trehalose, a disaccharide of glucose, and sucrose (which consists of a fructose and a glucose ring connected by a glycosidic bond) can be viewed as naturally occurring stabilizing agents.’
- ‘For example, bird-pollinated plants can secrete floral nectars containing the disaccharide sucrose, the monosaccharides glucose and fructose, or mixtures of these three sugars.’
