一般描述

β-丙氨酸是肌肽的一种限速前体,而肌肽则是一种以高浓度存在于人骨骼肌中的胞浆二肽。

应用

β-丙氨酸可作为参考标准品用于测定以下物质中的β-丙氨酸:
  • 马铃薯块茎,通过气相色谱-质谱(GC-MS)。
  • 人血浆、尿液、脑脊液样品,通过液相色谱-串联质谱(LC-MS/MS)。
  • 纹状体微透析样品,通过苯二甲醛-巯基乙醇衍生物的高效液相色谱-荧光检测(HPLC-FLD)。
  • 发酵豆酱清麴酱,通过在选择离子监测(SIM)模式和主成分分析(PCA)模式下运行的GC-MS。

生化/生理作用

β丙氨酸是一种 β− 氨基酸,是泛酸的组分,是组氨酰基抗氧化剂二肽肌肽和鹅肌肽生物合成中的限速氨基酸。内源性 β-氨基酸,是甘氨酸受体的非选择性激动剂和G蛋白偶联孤儿受体TGR7(MrgD)的配体。 β-丙氨酸通量通过维持海洋生物、植入前小鼠胚胎和暴露于缺氧应激的哺乳动物细胞的渗透稳定性而发挥细胞保护作用。
