L-tryptophan Powder
Melting Point of L-tryptophan L-tryptophan decomposes upon heating rather than melting cleanly, with a decomposition temperature around 289–290°C. This thermal instability means it can degrade under high-temperature conditions, especially in the presence of oxygen.Optical Activity As a chiral molecule (with a chiral center at the α-carbon), L-tryptophan exhibits optical activity. It rotates plane-polarized light to the left (levorotatory), with a specific rotation ([α]ᵈ²⁰) of approximately -31.5° to -33.0° in 1 M hydrochloric acid solution. Chemical PropertiesMolecular Structure and Functional Groups Its chemical formula isC11H12N2O2, with a molecular weight of 204.23 g/mol. The structure includes:An amino group (-NH₂) and a carboxyl group (-COOH) attached to the α-carbon (typical of amino acids).An indole ring as its side chain, which is responsible for many of its unique chemical reactions and biological activities.
