| Hazard Information | Back Directory | [Uses]
Penta-alanine (Penta-L-alanine) is a petide. Penta-alanine can be used for neurological disease research[1][2]. | [Biochem/physiol Actions]
L-Alanine has wide range of applications as food additive and as a component in infusion solutions. It is also used as a precursor for chemical and pharmaceutical products. In a penta-alanine system, resampling helps to increase the efficacy of a “fast-switch” equilibrium sampling protocol. | [References]
