D-Asparagine monohydrate is a chiral amino acid derivative primarily used in biochemical and pharmaceutical research. As the D-enantiomer of asparagine, it serves as a building block in the synthesis of D-peptides and unnatural amino acid sequences, which are valuable for studying enzyme stereospecificity and developing therapeutics with altered pharmacokinetics. It is employed in microbiological studies for organisms that utilize D-amino acids, such as certain bacteria. In cell culture applications, it is used selectively to investigate amino acid transport, metabolism, and enantiomer-specific effects on cellular functions, rather than as a standard nutrient (which is typically the L-form). Its high purity, stability, and solubility in aqueous solutions make it suitable for precise experimental protocols in molecular biology and drug discovery.
