一般描述
L-组氨酸是一种亲水性必需氨基酸，其具有含有咪唑基的碱性侧链。
生化/生理作用
L-组氨酸可由ATP、5-磷酸核糖-1-焦磷酸（PRPP）和谷氨酰胺生物合成。这种必需氨基酸可被组氨酸酶、尿苷酶和咪唑酮丙酸酶降解为谷氨酸；它也是组氨酸脱羧酶作用的组胺前体。

Protein aggregation can affect the quality of protein-based therapeutics. Attempting to unravel factors influencing protein aggregation involves systematic studies. These studies often include sodium azide or similar preservatives in the aggregation buffer. This work shows effects of azide on aggregation

Elucidating how a population of non-growing bacteria generates mutations improves our understanding of phenomena like antibiotic resistance, bacterial pathogenesis, genetic diversity and evolution. To evaluate mutations that occur in nutritionally stressed non-growing bacteria, we have employed the strain B. subtilis
