L-α-Aminoadipic acid is primarily used in biochemical research as a key intermediate in the study of lysine biosynthesis and degradation pathways. It plays a significant role in understanding metabolic processes in microorganisms, plants, and animals. Additionally, it is utilized in the development of antibiotics and other pharmaceuticals, particularly in the synthesis of beta-lactam antibiotics. Its application extends to the field of enzymology, where it serves as a substrate for studying enzyme kinetics and mechanisms. In medical research, elevated levels of L-α-Aminoadipic acid have been identified as a potential biomarker for type 2 diabetes and insulin resistance. In industrial biotechnology, it is explored for its potential in producing bio-based chemicals and materials.
