Tryptophan (symbol Trp or W) is an α-amino acid that is used in the biosynthesis of proteins. Tryptophan contains an α-amino group, an α-carboxylic acid group, and a side chain indole, making it a non-polar aromatic amino acid. It is essential in humans, meaning that the body cannot synthesize it and it must be obtained from the diet. Tryptophan is also a precursor to the neurotransmitter serotonin, the hormone melatonin, and vitamin B3. It is encoded by the codon UGG.
Like other amino acids, tryptophan is a zwitterion at physiological pH where the amino group is protonated (–NH3; pKa= 9.39) and the carboxylic acid is deprotonated ( –COO; pKa= 2.38).

Minimizing Cancer Risk: Understanding the Relationship Between Acrylamide, Advanced Glycation End Products, and Cooking Tips Tweet Follow @AZSPerformance In recent years, concerns about cancer risk associated with dietary choices have gained significant attention. Researchers have identified two substances, acrylamide and advanced glycation end products (AGEs), that are formed during certain cooking processes and have been linked to an increased risk of cancer. In this article, we will explore the connection between acrylamide, AGEs, and cancer, as well as provide practical tips to help you reduce your exposure to these potentially harmful compounds. Acrylamide and Cancer Risk: Acrylamide is a chemical compound that forms naturally during high-temperature cooking methods, such as frying, baking, and roasting. It is commonly found in foods like potato ...
