体外研究 |
Using 4-nitorophenol (pNP)-glycopyranosides as pseudosubstrates, the amount of liberated pNP from the 4-Nitrophenyl αD-galactopyranoside is significantly higher than that from the other pNP-glycopyranosides at pH 4.0 whereas no activity was detected at pH 7.0. The digestion assays using 4-nitrophenyl (pNP) glycopyranosides as artificial substrates shows that yieldin liberated galactose residues from 4-Nitrophenyl α-D-galactopyranoside mainly at pH 4.0, i.e. the pH level where yield threshold is decreased at most |
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系，公式为：
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
摩尔浓度计算公式
用本工具协助配置特定浓度的溶液，使用的计算公式为：
开始浓度 x 开始体积 = 最终浓度 x 最终体积
稀释公式
稀释公式一般简略地表示为：C1V1 = C2V2 ( 输入 输出 )
