应用

L-胱氨酸已被用作星形胶质细胞条件培养基的补充剂,用于培养脑星形胶质细胞。它已被用于多种技术,如HPLC-FD、UHPLC-UV、UHPLC-MS和三重四极杆串联质谱(UHPLC-MS/MS),以区分蓝藻神经毒素BMAA(β-N-甲基氨基-L-丙氨酸)与其他二氨基酸。
L-胱氨酸已被用作卵母细胞培养基的补充剂,用于改善卵母细胞成熟和胚胎发育的单性生殖。

生化/生理作用

胱氨酸尿症的特征在于L-胱氨酸的肾转运和排泄。半胱氨酸是与生长、繁殖、维持和免疫相关的功能性氨基酸之一。半胱氨酸是蛋白质中二硫键的来源,并且与硫转运有关。在生理pH下,半胱氨酸经过快速氧化,形成胱氨酸。半胱氨酸或胱氨酸的可用性降低,会影响白细胞代谢。L-胱氨酸是动脉平滑肌细胞的氧气产生和LDL(低密度脂蛋白)修饰所必需的。
