Interactions The amino acid compounds have different quantum yields, and distinct absorption and emission profiles. They can also change the spectral profile by reacting with each other; for example, ...

"If you move out to 317 nm there is a tail of the tryptophan excitation spectrum, where the absorption coefficient drops by a couple of orders of magnitude but is still sufficient for excitation," ...

The researchers discovered that when the virus remains in the gut long after the original COVID infection, tryptophan absorption is reduced and therefore, serotonin is depleted. This leads to a ...
