  1. Question 1

    Q1. When glucose and fructose combine to form sucrose, a specific bond forms between the aldehyde group of one and the keto group of the other. What is this linkage called?

    • A) 1,4-glycosidic linkage
    • B) 1,2-glycosidic linkage
    • C) 1,6-glycosidic linkage
    • D) 2,4-glycosidic linkage

    Answer: 1,2-glycosidic linkage

    Explanation: Sucrose involves a 1,2-glycosidic bond between glucose and fructose. 1,4-linkages are typical for linear chains like maltose or amylose.
