Is L-Tryptophan The Same As Tryptophan?

Publish Time: 2020-05-04     Origin: Site

Tryptophan is a restricted amino acid for pigs and must be obtained from an exogenous supply. When tryptophan is deficient in livestock and poultry, the conversion efficiency of feed will be reduced, and the animals will suffer from growth stagnation and weight loss.

  • What is L-Tryptophan?

  • Application of Tryptophan



What is Tryptophan?


Tryptophan, β-indolyl alanine, is white or slightly yellow crystalline or crystalline powder; odorless, slightly bitter. It is slightly soluble in water, very slightly soluble in ethanol, insoluble in chloroform, easily soluble in formic acid, and soluble in sodium hydroxide test solution or dilute hydrochloric acid. Tryptophan is an important precursor of auxin biosynthesis in plants. Its structure is similar to IAA and it is common in higher plants.


Tryptophan can participate in the renewal of plasma proteins in animals, and can promote the function of riboflavin. It can also help the synthesis of niacin and heme. It can significantly increase the antibodies in the fetuses of pregnant animals. Promote lactation. When tryptophan is deficient in livestock and poultry, growth stagnation, weight loss, reduced fat accumulation, and testicular atrophy in male and female animals. It is used in medicine to prevent and treat rickets.

 

What is L-Tryptophan?



L-Tryptophan is also known as α-aminoindolyl propionic acid, molecular formula: C11H12N2O2, white to yellow-white crystal or crystalline powder. No odor or slight odor, coloring for long time. It is more stable when heated in the dark with acid. It is easy to decompose when coexisting with other amino acids, sugars and aldehydes. Used as food fortifier and antioxidant. Also used in medicine and other aspects. Synthesized from indolaldehyde. It can also be prepared by trypsin decomposition and synthesis.


People: Nutritional supplements. Antioxidants. Tryptophan is the precursor of the human body's important neurotransmitter -5-hydroxytryptamine, which is one of the essential amino acids of the human body; it is used as a nutritional supplement for pregnant women and special milk powder for infants and young children; it is used for the treatment of niacin deficiency (pellagra) Medicine; as a tranquilizer, it can regulate mental rhythm and improve sleep.


Animals: Promote animal feeding, reduce stress response, improve animal sleep, can also increase fetal and pup antibody, and improve lactation of dairy animals. Reduce the amount of high-quality protein in the diet, save feed costs, reduce the amount of protein protein in the diet, and save formula space.


Application of Tryptophan


For animals, tryptophan cannot be synthesized in animals, and tryptophan in plant-based feeds usually cannot meet the needs of livestock and poultry. Therefore, tryptophan is also an amino acid necessary for animal growth. For example, tryptophan is needed during pig growth. The tryptophan requirement recommended by NRC (1988) is 0.12% (2.3 g / d). The tryptophan requirement for growing pigs before 50kg is O.13%. A study by Hamilton (1993) showed that the best performance was achieved when the tryptophan level in the diet of 20-50 kg growing pigs was 0.14%. Now let's introduce tryptophan and its application effect in pig feed.


Tryptophan scientific name 2-amino-3-indolyl propionic acid. It is an aromatic, heterocyclic, non-polar alpha amino acid. L-tryptophan is one of the 20 common amino acids that make up proteins. It is an essential amino acid and a glucogenic amino acid in mammals. In nature, D-tryptophan is found in certain antibiotics. Tryptophan is an important nutrient. It can participate in the renewal of plasma proteins in animals, and can promote the function of riboflavin, and also contribute to the synthesis of niacin and heme. It can significantly increase the antibodies in the fetal calves of pregnant animals, and promote lactation in lactating cows and sows. effect. When tryptophan is deficient in livestock and poultry, growth stagnation, weight loss, reduced fat accumulation, and testicular atrophy in male and female animals. In addition, it can also be used in medicine to prevent and treat rickets.
