Lactobionic Acid

Lactobionic Acid (CAS No.: 96-82-2) is a naturally derived bionic acid composed of a gluconic acid moiety linked to a galactose unit, classified within polyhydroxy acids and widely utilized as a multifunctional reagent in biochemical and pharmaceutical research. It exhibits notable antioxidant and metal-chelating properties, enabling modulation of redox balance and sequestration of transition metal ions, which in turn can influence cellular metabolism and signaling pathways associated with oxidative stress responses. Experimental studies indicate that Lactobionic Acid can perturb microbial viability through mechanisms involving disruption of DNA repair processes, inhibition of protein synthesis, and induction of oxidative stress, suggesting utility in investigations of antimicrobial resistance and metabolic inhibition, typically observed at low micromolar to millimolar concentrations depending on the model system. In addition, its physicochemical stability and hydrophilic nature support its application as a stabilizing and buffering component in drug delivery research, where it contributes to improved formulation stability and controlled release profiles. Lactobionic Acid is also employed in cell-based assays and biomaterial development to study moisture retention, extracellular matrix interactions, and biocompatibility, with experimental concentrations and conditions varying according to specific assay design and research objectives.
