Pyridoxylamine is primarily used in biochemical research to study enzyme mechanisms, particularly those involving vitamin B6-dependent enzymes. It serves as a cofactor analog in investigations of transamination, decarboxylation, and other metabolic processes. In medical research, it is utilized to explore its potential therapeutic effects, such as its role in managing diabetic complications due to its ability to inhibit the formation of advanced glycation end products (AGEs). Additionally, it is employed in the development of nutritional supplements aimed at supporting metabolic health and addressing vitamin B6 deficiencies. Its antioxidant properties also make it a subject of interest in studies related to oxidative stress and cellular protection.
