OEM Manufacturer Chicken Feeds - L-Tryptophan CAS 73-22-3 for Feed Grade – Honray Detail:
Usage:
L-Tryptophan (Abbreviated Try) is one of human and animal essential amino acids. But it can’t be synthesized by the body.
Like other amino acids, L-Tryptophan is one of the building blocks of protein. But unlike some amino acids, L-Tryptophan is considered essential because the body can’t manufacture its own. L-Tryptophan plays many roles in animals and humans alike. But perhaps most importantly, it is an essential precursor to a number of neurotransmitters in the brain. As such, L-Tryptophan is the only substance normally found in the diet that can be converted into serotonin. Since serotonin is converted in the brain into melatonin, L-Tryptophan clearly plays a role in balancing mood and sleep patterns.
Used as nutritional supplement and antioxidant.
1. Used in the animal feed to improve animal feed intake, weaken stress reaction, improve animal sleeping.
2. Used in the animal feed to increase the antibody of fetus and young animals.
3. Used in the animal feed to improve milk secretion of dairy cattle.
4. Used in the animal feed to reduce the amount of high protein ration and save feed cost.
As a nutritional supplement, L-tryptophan is to make up amino acid infusions and comprehensive amino acid preparations together with other essential amino acids.
L-tryptophan is made by microbial fermentation which the glucose, yeast extract, ammonium sulfate are used as raw materials and get refined by membrane filtration, ion exchange, crystallization and drying process.
