Nα-Acetyl-L-lysine is widely used in biochemical research as a modified amino acid to study protein structure and function. It serves as a precursor in the synthesis of peptides and proteins, particularly in cases where acetylation is required to mimic post-translational modifications. This compound is also employed in the development of nutritional supplements aimed at promoting muscle recovery and overall health. Additionally, it finds application in cosmetic formulations, where it helps to improve skin hydration and elasticity by supporting collagen production. In the pharmaceutical industry, Nα-Acetyl-L-lysine is investigated for its potential therapeutic effects, including its role in enhancing cellular repair and reducing oxidative stress.
