Biological Activity

Description	L-tryprophan is an essential amino acid that acts like a natural mood regulator that is necessary for normal growth in infants and for nitrogen balance in adults.

In Vivo
In vivo	L-Tryptophan suppresses both serum glucose and insulin levels after oral glucose administration and inhibits glucose absorption from the intestine. It increases glucose-associated energy expenditure in rats in vivo. L-Tryptophan suppresses the rapid rise in blood glucose after a glucose-rich meal and lessens the burden of insulin secretion from β-cells. Oral administration of L-tryptophan is more effective than intraperitoneal injection^[1].
Animal Research	Animal Models	Four-week-old male normal Sprague-Dawley rats
	Dosages	62.5 mg/kg
	Administration	Oral administration

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
