3,5-二硝基水杨酸（DNS）是蔗糖合成酶SS-I（分解方向）活性检测试剂盒中的核心显色剂，其原理为：SS-I催化蔗糖和UDP生成果糖，果糖与DNS在加热条件下反应生成棕红色产物，该产物在540 nm处具有特征吸收峰，通过测定吸光度可定量果糖生成量，进而计算酶活性。
3,5‑Dinitrosalicylic acid (DNS) is the core chromogenic reagent in the assay kit for the cleavage direction activity of sucrose synthase (SS‑I). The principle is as follows: SS‑I catalyzes the reaction of sucrose and UDP to produce fructose. The generated fructose reacts with DNS under heating conditions to form a brown‑red product, which exhibits a characteristic absorption peak at 540 nm. By measuring the absorbance, the amount of fructose produced can be quantified, and the enzyme activity can be subsequently calculated.
