Alias: L-tryptophan; Aminoindole propionic acid; Aminoindole propionic acid; L- α- Amino-3-indolyl-1-propionic acid; L-Pancreatic Protein Amino Acid
Molecular formula: C11H12N2O2
Molecular weight: 204.23
Properties: This product is white or off white to yellowish crystalline powder, odorless or slightly odorous, L-type slightly bitter, DL type, D-type slightly sweet. Decomposition at 289 ° C, slightly soluble in water, insoluble in ethanol; It is dissolved in dilute acid or alkali, colored when exposed to light for a long time, and generates a small amount of indole when heated with water. If heated in the presence of sodium hydroxide and copper sulfate, a large amount of indole is generated. It is stable when heated with acid in the dark, and is easy to decompose when coexisting with other amino acids, sugars, and aldehydes.
Use: Tryptophan is a heterocyclic amino acid, which is an important essential amino acid for human body. It is widely used in the food field.
1. It is used for nutrition fortified food. It is used as the third feeding amino acid. Tryptophan contained in egg white protein, fish meat, corn flour, etc. is a limiting amino acid, while it is less contained in grains such as rice. Chroma can be combined with lysine, methionine and threonine to strengthen amino acids.
2. Tryptophan is an important component of amino acid infusion and comprehensive amino acid preparations.
3. It is used as a nutritional supplement for pregnant women and special milk powder for young infants.
