Chemical & Physical Properties:
Appearance: White powder
Boiling Point:447.9℃ at 760 mmHg
Odorless, slightly bitter taste, slightly soluble in water (1.14%, 25℃), but hardly soluble in ethanol. Soluble in dilute acid or alkali. [α]D+2.8(5mol/LHCl), [α]D+6.2(0.5mol/LNaOH). Long-term light will be colored. Co-heating with water produces a small amount of indole. Heating in the presence of sodium hydroxide and copper sulfate produces a large amount of indole. It is more stable when heated in the dark with acid, but it is extremely heated when it coexists with other amino acids, sugars, and aldehydes. Easy to decompose. When protein is decomposed with acid, tryptophan is completely decomposed.
