Biochem/physiol Actions
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。

Amino acids provide the most universal and important inhibitory (gamma-aminobutyric acid (GABA), glycine) and excitatory (glutamate, aspartate, cysteic acid, cysteine sulphinic acid) neurotransmitters in the brain. An anticonvulsant action may be produced (1) by enhancing inhibitory (GABAergic) processes, and (2)

Moderate hyperhomocysteinemia is associated with several diseases, including coronary artery disease, stroke, Alzheimer's disease, schizophrenia, and spina bifida. However, the mechanisms for their pathogenesis are unknown but could involve the interaction of homocysteine or its metabolites with molecular targets such
