4-Aminohippuric acid (p-Aminohippuric acid) is a coordination ligand for metal ions (such as Cu ²⁺, Fe ³⁺, Hg ²⁺) and a functionalization reagent for nanomaterials. 4-Aminohippuric acid can coordinate with metal ions or modify the surface of materials such as carbon nanotubes and gold nanoparticles through amino and carboxyl groups. 4-Aminohippuric acid can form stable complexes with metal ions or participate in the synthesis of nanomaterials as a reducing agent/stabilizer, enriching metal ions or giving nanoparticles peroxidase-mimicking activity. 4-Aminohippuric acid can be used to construct highly sensitive electrochemical sensors or colorimetric sensors to detect and quantitatively analyze heavy metal ions such as copper, iron, and mercury in environmental water samples and biological samples. 4-Aminohippuric acid may also be a biomarker for attention-deficit/hyperactivity disorder (ADHD) .

D-Histidine	Microorganisms Source Classification	Mitochondrial Metabolism Bacterial
D-Histidine is an anti-biofilm agent that targets bacterial quorum sensing systems (such as RhlI/RhlR pathway) and has antibacterial activity. D-Histidine works by non-covalently binding to bacterial regulatory factors or copper ion complexes, selectively inhibiting bacterial biofilm formation and motility. D-Histidine downregulates quorum sensing-related gene expression, reduces the synthesis of virulence factors (such as alginate and proteases), and interferes with bacterial membrane stability, inhibiting biofilm formation, promoting the disintegration of mature biofilms, and enhancing antibiotic sensitivity. D-Histidine is also an efficient catalyst for the salt-induced peptide formation (SIPF) reaction, which promotes the condensation of amino acids to form dipeptides (such as dialanine and dilysine) by forming a complex with copper ions (Cu ²⁺) .
