S-SC能够水解蔗糖变成相应的单糖而被机体吸收,其酶促作用产物与土壤中有机质、氮、磷含量,微生物数量及土壤呼吸强度密切关,是评价土壤肥力的重要指标。 测定原理:S-SC催化蔗糖降解产生还原糖,进一步与3,5-二硝基水杨酸反应,生成棕红色氨基化合物,在510nm有特征光吸收,在一定范围内510nm光吸收增加速率与S-SC活性成正比。
S-SC hydrolyzes sucrose into the corresponding monosaccharides for absorption by the organism. Its enzymatic products are closely related to soil organic matter, nitrogen and phosphorus contents, microbial counts, and soil respiration intensity, making it an important indicator for evaluating soil fertility. Determination principle: S-SC catalyzes the degradation of sucrose to produce reducing sugars, which further react with 3,5‑dinitrosalicylic acid to form a reddish‑brown amino compound with characteristic light absorption at 510 nm. Within a certain range, the rate of increase in absorbance at 510 nm is proportional to S-SC activity.
