TestHub · Accepted Answer

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.
