WebOct 12, 2024 · Tryptophan (Trp) is an aromatic amino acid which is synthesized through the shikimate/chorismate pathway. Behind that this amino acid is part of proteins; the relevance of Trp resides as a precursor of secondary metabolism which includes relevant molecules such as auxin (indole-3-acetic acid, IAA), serotonin and melatonin which have a wide … WebWe report a selective, mild, and efficient C–H functionalization of tryptophan and tryptophan-containing peptides with activated α-bromo-carbonyl compounds under visible-light irradiation. The protocol efficiency is outlined by the wide substrate scope and excellent tolerance of sensitive functional groups present in the amino acid side chains. WebApr 20, 2015 · We demonstrate the occurrence of tryptophan (Trp) to heme electron transfer (ET) in ferrous myoglobins by ultrafast UV spectroscopy.
