L-Histidine monohydrochloride monohydrat

L-Histidine is a positively charged, proteinogenic amino acid with an aromatic imidazole side chain, making it a key catalytic residue in enzyme active sites. It is widely used in biochemical research, including studies of enzyme mechanisms, protein structure-function, and in vitro assays modeling metabolic pathways such as nucleotide and histidine biosynthesis.
