胱氨酸（Cystine）协助皮肤的形成，且对解毒作用很重要，借由减低身体吸收铜的能力，胱氨酸保护细胞免于铜中毒。当它被代谢时，会释放硫酸，而硫酸会与其他物质产生化学作用，增加整个代谢系统的解毒功能。此外，它辅助胰岛素的供给，胰岛素是人体利用糖和淀粉所必需的。也能促进细胞氧化还原，使肝功能旺盛，促进白细胞...

侧链含硫的基本氨基酸有两种,半胱氨酸(cysteine,Cys)和甲硫氨酸(methionine,Met)。 半胱氨酸顾名思义,就是胱氨酸的一半。胱氨酸(Cystine)是在从膀胱结石(cystolith)中发现的,所以命名为胱氨酸。两个半胱氨酸被氧化,通过二硫键连接到一起,就形成了胱氨酸。
1.1.3 Cystine Stones Cystine stones account for 1%–2% of stone formers, although they represent a higher percentage of stones in children (about 5%). Cystinuria is a genetic cause of kidney stones with an average prevalence of 1 in 7000 births. Cystine stones are predominantly seen in pati...
