一般描述
Ammonium dihydrogen phosphate (ADP) is a crystal material and is a member of large family of compounds which possess a chemical formula:MH2XO4 .[1]
应用
- Capillary-seeding crystallization and preliminary crystallographic analysis of a solvent-tolerant elastase from Pseudomonas aeruginosa strain K.: This research employs ammonium phosphate monobasic in the crystallization process of elastase from Pseudomonas aeruginosa. The study provides crucial structural data that can aid in understanding the enzyme′s function and its potential industrial applications (Ali et al., 2013).
生化/生理作用
Ammonium dihydrogenphosphate (ADP) exhibits non-linear optical (NLO) and electro-optic (EO) properties.[1]
