Introduction to the metabolic pathways and functions of Typetophan
There are three metabolic pathways for tryptophan in the body. The kynurenine metabolic pathway (KP) is the metabolism of tryptophan in indoleamine 2,3-dioxygenase (IDO) or tryptophan 2,3-dioxygenase (Tryptophan). Kynurenine (Kyn) is generated under the action of 2,3-dioxygenase (TDO), and through multi-stage enzymatic reactions, quinolinic acid, pyridine carboxylic acids, nicotinamide adenine dinucleotide (NAD) and nicotinamide purine dinucleotide phosphate (NADP) are generated. The serotonin metabolic pathway (Serotonin Pathway) generates serotonin (5-hydroxytryptamine, 5-HT) through hydroxylation and decarboxylation and is involved in neurodevelopment. The aryl hydrocarbon receptor metabolic pathway (AhR Pathway) generates indole derivatives, such as indole and indole acetic acid, through deamination and decarboxylation under the action of a variety of microorganisms.

Tryptophan, an essential amino acid, boasts numerous health benefits. It serves as a precursor for the production of serotonin, a neurotransmitter that plays a crucial role in regulating mood, appetite, and sleep. By increasing serotonin levels in the brain, tryptophan can help alleviate symptoms of depression, anxiety, and insomnia.
Furthermore, tryptophan is also involved in the synthesis of melatonin, a hormone that promotes sleep and enhances the immune system. Its ability to support mental well-being and overall health makes tryptophan a valuable addition to various dietary supplements and health products.
