  1. Question 1

    Q1. During the synthesis of sucrose from glucose and fructose, as shown in biochemical diagrams, what is the specific nature of the glycosidic bond?

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

    Answer: 1,2-glycosidic linkage

    Explanation: Sucrose is formed by a 1,2-glycosidic linkage between glucose and fructose. 1,4-linkage is tempting as it is common in maltose and lactose.
