L-Tryptophan

Catalog No.S3987 Batch:S398701

Technical Data

Formula

C₁₁H₁₂N₂O₂

Molecular Weight

204.23

CAS No.

73-22-3

Solubility (25°C)*

In vitro

DMSO

11 mg/mL (53.86 mM)

In vivo (Add solvents to the product individually and in order)

Clear solution

5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O

0.55mg/ml

Taking the 1 mL working solution as an example, add 50 μL of 11 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

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	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].
