产品说明 应用 氨基酸分析的内标。 生化/生理作用 L-半胱磺酸是一种 L-半胱氨酸的氧化产物。L-半胱磺酸是半胱氨酸亚磺酸的类似物，可用于研究脑中的兴奋性氨基酸，例如与半胱氨酸亚磺酸受体结合的氨基酸。L-半胱磺酸是几种大鼠代谢型谷氨酸受体(mGluRs)的有用的激动剂。
L-半胱磺酸是含硫的天冬氨酸类似物，其可以用作细菌天冬氨酸：丙氨酸反向转运体(AspT)交换天冬氨酸和其他天冬氨酸生物系统的竞争性抑制剂。L-半胱磺酸用于单体表面活性剂的开发。 基本信息 | 线性分子式 | HO3SCH2CH(NH2)CO2H·H2O | | 分子量 | 187.17 | | Beilstein | 3714036 | | MDL编号 | MFCD00149544 | | PubChem化学物质编号 | 24858207 | | NACRES | NA.26 |
