Product description:

Tryptophan (symbol Trp or W) is an α-amino acid that is used in the biosynthesis of proteins. Tryptophan contains an α-amino group, an α-carboxylic acid group, and a side chain indole, making it a non-polar aromatic amino acid. It is essential in humans, meaning the body cannot synthesize it; it must be obtained from the diet. Tryptophan is also a precursor to the neurotransmitter serotonin, the hormone melatonin and vitamin B3. It is encoded by the codon UGG.

Application:

Tryptophan is present in most protein-based foods or dietary proteins. It is particularly plentiful in chocolateoats, dried datesmilkyogurtcottage cheesered meateggsfishpoultrysesamechickpeasalmondssunflower seedspumpkin seedsbuckwheatspirulina, and peanuts. Contrary to the popular belief that cooked turkey contains an abundance of tryptophan (with this being used as an explanation for sleepiness following consumption of the meat), the tryptophan content in turkey is typical of poultry.

Function:

1. L-Tryptophan is an important nutrient.
2. L-Tryptophan takes part in the renewal of animal blood plasma protein in the body
3. L-Tryptophan helps nicotinic acid and the synthesis of hemoglobin. It can significantly increase antibody in pregnant animals baby.
4. L-Tryptophan can promote lactation of cows and sows.
