General description
正缬氨酸(Norvaline)是一种非蛋白质α-氨基酸，又名DL-α-氨基戊酸。它产自大肠杆菌等革兰氏阴性菌，也是枯草芽孢杆菌所产抗真菌肽的组分。
Application
DL-正缬氨酸作为内部标准品，已用于：
- 气相色谱-质谱法(GC-MS)分析哺乳动物培养细胞的代谢物
- 将半胱氨酸和胱氨酸转化为Cys MPA(S-2-羧乙基硫代-L-半胱氨酸)，并采用高效液相色谱(HPLC)分析仪进行定量分析
- 液相色谱法分析卵母细胞样本中的游离氨基酸
Biochem/physiol Actions
DL-戊氨酸是一种神经递质。
正缬氨酸介导促进一氧化氮生成的生理和病理生理过程。可用于治疗阿尔茨海默病，并可有效抵抗大鼠模型的代谢综合征。正缬氨酸冷却到190K以下后会发生相变，因此可用于分子机器。DL-正缬氨酸可作为含线性侧链的脂肪族α-氨基酸的多态性和分子动力学研究的原型，影响蛋白质的活性、稳定性和侧链堆积。

dl-Norvaline is a molecular crystal at room temperature and it undergoes a phase transition when cooled below 190 K. This phase transition is believed to be Martensitic, thus making it of particular interest for molecular machines. In this paper we

A less frequently employed Escherichia coli strain W, yet possessing useful metabolic characteristics such as less acetic acid production and high L-valine tolerance, was metabolically engineered for the production of L-valine. The ilvA gene was deleted to make more pyruvate

The aim of the present study was to determine whether or not lipopolysaccharide from Actinobacillus actinomycetemcomitans could stimulate arginase activity in a murine macrophage cell line (RAW264.7 cells). RAW264.7 cells were treated with A. actinomycetemcomitans-lipopolysaccharide or lipopolysaccharide from Escherichia coli
