5-Benzyloxy-DL-tryptophan is a reagent used in chemical synthesis.

Arginine is an essential amino acid found in food and plant sources, and many biological systems. D-Arginine specifically can inhibit arginine decarboxylase enzymes and also functions as a metabolite.

L-Albizziine is a white to slightly off-white crystalline powder that is used as a competitive inhibitor of asparagine synthetase in mammalian cells. It can also be used as an inhibitor of both glutamate synthase in ectomycorrhizal fungal isolates, and glutamine metabolism in microbes.

L-Cysteine is a non-animal-derived, sulfur containing proteinogenic amino acid that is important in the maintaining of normal iron levels in the body and plays a critical role in reducing oxidative damage and inflammation. While naturally produced by the human body, L-Cysteine can also be obtained through certain dietary sources. Research indicates that L-Cysteine is essential in regulating protein oxidation and cellular injury responses. Additionally, it contributes to immune function by interacting with Toll-like receptors, key proteins involved in inflammation and immune responses. L-Cysteine enhances immune defense by stimulating antibody production, essential for combating infections. As a key amino acid, L-Cysteine participates in various biochemical processes, including protein and DNA synthesis, and regulates gene expression through its influence on promoter response elements.
