一般描述
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。
应用
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
生化/生理作用
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。

Metabolism plays a central role in virtually all diseases, including diabetes, cancer, and neurodegeneration. Detailed analysis is required to identify the specific metabolic pathways dysregulated in the context of a given disease or biological perturbation. Measurement of metabolite concentrations can

Bonefishes (Albula spp.) are classified within the superorder Elopomorpha, which is comprised of over 1000 species that share a unique leptocephalus larval stage. Bonefishes have a circum-tropical distribution, inhabiting inshore shallow water flats and gathering in presumptive nearshore pre-spawn aggregations

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

Oxidation-reduction (redox) reactions are ubiquitous in biology and typically occur in specific subcellular compartments. In cells, the electron transfer between molecules and organelles is commonly facilitated by pyridine nucleotides such as nicotinamide adenine dinucleotide phosphate (NADPH) and nicotinamide adenine dinucleotide

The NCN-pincer Pd-complex-bound norvalines Boc-D/L-[PdCl(dpb)]Nva-OMe (1) were synthesized in multigram quantities. The molecular structure and absolute configuration of 1 were unequivocally determined by single-crystal X-ray structure analysis. The robustness of 1 under acidic/basic conditions provides a wide range of N-/C-terminus
