Description

L-tryptophan is a neutral aromatic amino acid containing an indole group, and its form is white or slightly yellow leaf-like crystals or powder. Its solubility in water is relatively low, but it can dissolve in dilute acids or dilute alkalis, and it is relatively stable in alkaline solutions, but it will decompose in strong acids. Furthermore, L-tryptophan is slightly soluble in ethanol but insoluble in chloroform and ether.

Advantages:

Essential amino acids: The human body cannot synthesize L-tryptophan on its own and it must be obtained through diet or supplements.
Neurotransmitter precursors: Synthesize serotonin and melatonin to regulate mood, sleep and the biological clock.
Metabolic function: L-tryptophan is involved in protein synthesis and the generation of niacin (vitamin B3).
Physiological effects: L-tryptophan improves sleep quality and alleviates anxiety and depression. Promote the growth and development of infants and young children. L-tryptophan assists in regulating appetite and energy metabolism.

Application

Nutritional fortifier
Infant formula milk powder: L-tryptophan supplements essential amino acids and supports neural development.
Cereal products (such as breakfast cereal) : L-tryptophan makes up for the deficiency of tryptophan in plant protein.
Special diet: For people with malnutrition or digestive disorders.
Functional food
Sleep-inducing foods: When combined with vitamin B6, magnesium, etc., they can be made into beverages, gummy candies or dairy products to improve sleep by promoting the secretion of melatonin.
Emotional regulation foods: Snacks or beverages for stress relief (such as ready-to-drink tea, protein bars).
Flavor and processing assistance
L-tryptophan generates aromatic compounds during baking or heat treatment, enhancing the flavor of food (such as bread and processed meat products).L-tryptophan, as a metabolic substrate for probiotics, enhances the fermentation efficiency (such as in yogurt and douchi).
Sports nutrition food
Protein powder and energy bars: L-tryptophan optimizes the amino acid profile and promotes muscle synthesis and recovery.
Feed additive
L-tryptophan enhances the growth performance and stress resistance of animals.
