The biological activity of this molecule is of interest as a potential free radical scavenger (antioxidant), similar to that function of melatonin.[1] It also acts as an endogenous MAOI.

Tryptophan is the amino acid metabolized into 5-HTP, from which serotonin and subsequently melatonin can be produced. Melatonin appears to inhibit the tryptophan 2,3-dioxygenase (TDO) enzyme, which directs tryptophan away from production into 5-HTP by enhancing its catabolism.Inhibition of TDO via melatonin can enhance the amount of bioavailable tryptophan, independent of supplementation

Melatonin isn't necessary for this 'mistake' to occur - and I agree with Phen that the likely source of trace amounts emerges from earlier steps in the synthesis cascade of serotonin.

The hormone melatonin, which is known to have a range of important biological effects, has been prepared in a high-yielding route that features formation of the indole nucleus by radical cyclization. Mediation of the radical cyclization by tristrimethylsilylsilane (TTMSS) is more efficient than by N-ethylpiperidine hypophosphite According to TiHKAL, pure harmaline ingested orally may create a 5-8 hour intoxication. Taking 150 mg induced the following experience: In an hour and a quarter, there was a rapid-onset intoxication and I felt a little unstable. And a little bit numb.

Substituted tryptamines, or serotonin analogues, are organic compounds which may be thought of as being derived from tryptamine itself..

  1. Taking melatonin may inhibit an enzyme which turns tryptophan to 5-HTP, then to serotonin, and melatonin. We want to avoid that and allow the body to make DMT out of the tryptophan. I would like to add that perhaps adding 5-HTP to the mix will prevent the brain from converting tryptophan to 5-HTP since there is plenty of it available
