In non-reducing disaccharide, the reducing group of monosaccharides i.e. aldehydic or ketonic group are bounded. Which of the following disaccharide is a non-reducing sugar?

Step-by-step solution

This structure represents sucrose in which α - D - glucose and β - D - fructose is attached to each other by C 1 - C 2 glycosidic linkage. Since reducing groups of glucose and fructose are involved in glycosidic bond formation, this is considered as non-reducing sugar.
