When exposed to light of wavelength 254 nm, tryptophan was alsorapidlydegraded,although less quickly than in bright sunlight: 64% in the 5 itmol/L solution was destroyed after 15 mm exposure,whileatthelower concentration no detectable tryptophan remained after 30-mm exposure. Tryptophan in the su...
