應用
L-胱氨酸已被用于制备原液，该原液又通过光谱荧光流动注射法用于测定药物制剂以及尿液样品中的L-半胱氨酸和L-胱氨酸。
生化／生理作用
胱氨酸是合成保护细胞免受氧化应激的谷胱甘肽所必需的。一种特殊的 x (c)-半胱氨酸/谷氨酸反向转运蛋白可介导细胞摄取半胱氨酸以交换谷氨酸。半胱氨酸摄取抑制诱导神经元细胞毒性。

Glutamate binds to both excitatory neurotransmitter binding sites and a Cl(-)-dependent, quisqualate- and cystine-inhibited transport site on brain neurons. The neuroblastoma-primary retina hybrid cells (N18-RE-105) are susceptible to glutamate-induced cytotoxicity. The Cl(-)-dependent transport site to which glutamate and quisqualate (but

A flow injection configuration is proposed for the determination of L-cysteine and L-cystine individually and for mixtures of both analytes. The procedure is based on the rapid oxidation of L-cysteine by thallium(III) with concomitant formation of fluorescent thallium(I). The inclusion
