Formation of 5-Hydroxytryptamine in an Aqueous Solution of 5-Hydroxytryptophan treated with X-rays

Naturevolume 191pages383384 (1961) | Download Citation



IT has been found that 5-HT (5-hydroxytryptamine) is formed by the action of ultra-violet irradiation on 5-HTP (5-hydroxytryptophan) aqueous solution, as a result of a decarboxylation process1. It is of interest to investigate whether the same process takes place under the influence of X-irradiation.
