Description
- Application: L-Histidine has been used for characterization of ZnO nanorod in an attempt to develop a technique for the ultra-low level detection of l-histidine.[1]
- Biochem/physiol Actions: Precursor of histamine by action of histidine decarboxylase.
- Other Notes: Amino acid spacing in isotachophoresis on polyacrylamide gels - a critical evaluation[3]; Prevents circular DNA strand cleavage in a xanthine-xanthine oxidase system[4]; Growth requirement of various microorganisms[5].
