L-Tryptophan（Cat No.:R048596）is an essential aromatic amino acid with the molecular formula C₁₁H₁₂N₂O₂, required for protein synthesis and human health. It contains an indole functional group, making it a precursor to several biologically important molecules, including serotonin, melatonin, and niacin (vitamin B3). As the body cannot synthesize it, L-tryptophan must be obtained through the diet from sources like meat, dairy, eggs, and legumes. It plays a key role in regulating mood, sleep, and cognitive function. L-Tryptophan is also used in nutritional supplements and research in neuroscience and metabolic pathways.
