说明

蔗糖是一种丰富的二糖，是光合作用的最终产物。这种非还原糖由葡萄糖和果糖组成。它来自蔗糖。蔗糖主要在叶子中合成。
由于其有限的化学反应性，蔗糖在大多数植物中用作运输和储存分子。它可用于制备用于分离细胞/细胞器的密度梯度。蔗糖可作为补充剂用于植物，昆虫和细菌培养基中。另外，蔗糖也可用于几种酶测定。

一般描述

Sucrose, an abundant disaccharide, is the end product of photosynthesis. This nonreducing sugar is composed of glucose and fructose. It is obtained from cane sugar. Sucrose is predominantly synthesized in leaves.
 

应用

Sucrose has been used:
  • to perform cryoprotection for kidney tissues
  • as a component in the solid germination medium to germinate pollen grains
  • in the triphenyl-tetrazolium chloride (TTC) test to check the viability of pollen grains
  • in the cryoprotection of fixed brain tissues for immunohistochemistry

生化/生理作用

Sucrose is used as a transport and storage molecule in most plants due to its limited chemical reactivity. It can be used to prepare density gradients for the separation of cell/organelle. Sucrose can be used in the plant, insect, and bacterial culture media as a supplement. In addition, sucrose can also be used in several enzymatic assays.
