L-tryptophan and its metabolites can widely participate in the metabolic process of organisms. L-tryptophan catabolism can produce a variety of physiologically active substances, such as 5-tryptamine (5-HT) pigment, niacin, alkaloids, coenzymes and melatonin. These metabolites are widely involved in a variety of physiological activities. At the same time and participate in a variety of physiological regulation.
As one of the important metabolites of L-tryptophan, 5-HT is an important neurotransmitter in the human central nervous system, which can regulate human mental activities and control the excitatory expression of the nervous system. If the level of L-tryptophan in the blood of the human body decreases, it will cause insufficient supply of 5-TH in the brain, causing people to have depression, self-blame and other emotions, so the phenomenon of insufficient 5-TH supply will be found in patients with depression. Therefore, in the treatment of depression patients, if L-tryptophan is actively supplemented, the content of 5-TH in the patient's brain will be correspondingly increased, so that the patient's mood will be well controlled and the condition will be significantly relieved.
L-tryptophan is already listed as an antidepressant in the UK. Clinical studies have found that L-tryptophan combined with iron and vitamins can enhance their efficacy in the treatment of exercise-induced anemia, and can also treat peptic ulcers when used together with histidine.
At present, the importance of L-tryptophan has been paid more and more attention by people. Now the application of L-tryptophan is not only limited to traditional medicine, food and feed additive industries, but also has more applications in some new fields. For example, amino acid whitening agents are gradually applied to the cosmetic industry. In addition, many amino acid drinks as healthy drinks are popular in developed countries such as Europe and the United States. With the advancement of science and technology, it is believed that people will have more explorations and discoveries on the use of tryptophan.
