L-tryptophan

• 

L-tryptophan’s physical and chemical properties—rooted in its indole ring structure and amphoteric nature—dictate its stability, reactivity, and biological roles, making it a unique and vital amino acid in both natural systems and industrial applications.

Heat Stability of L-tryptophan

It is relatively unstable under prolonged heating, especially in alkaline environments. High temperatures can cause decarboxylation (loss of CO₂) or deamination (loss of NH₃), as well as Maillard reactions with reducing sugars, which browning and reduce its bioavailability.
