Abstract Tryptophan possesses two sets of emissions, each one of which has one short-lived emission and one long-lived emission. The excitation by π-π absorption at 280 mμ gives u.v. fluorescence and blue phosphorescence under certain conditions, e.g. frozen in an aqueous solution containing glucose or methanol.

Tryptophan in health and disease
2020Tryptophan (TRP), an essential amino acid in mammals, is involved in several physiological processes including neuronal function, immunity, and gut homeostasis. In humans, TRP is metabolized via the kynurenine and serotonin pathways, leading to the generation of biologically active compounds, such as serotonin, melatonin and niacin.

Tryptophan Metabolism in Rabbits
2003Enzyme activities involved in tryptophan metabolism along the kynurenine pathway were studied in male New Zealand white rabbits. Activities are expressed both as specific activity and per g of fresh tissue. Liver tryptophan 2,3-dioxygenase activity (TDO), when assayed in either the absence (holoenzyme) or presence of added haematin (apoenzyme), did not
