D-Tryptophan MSDS


(R)-2-Amino-3-(3-indolyl)propionic acid

D-Tryptophan C??? ??, ??, ??

??? ??

white powder

??

An essential amino acid found in naturally produced pedtides. Unlike its stereoisomer, L-tryptophan, it is not used in structural or enzyme proteins.

??

ChEBI: The D-enantiomer of tryptophan.

?? ??

White solid.

??? ?? ??

Slightly soluble in water.

?? ???

Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

????

Flash point data are not available for D(+)-Tryptophan, but D(+)-Tryptophan is probably combustible.

Pharmaceutical Applications

Preclinical and emerging clinical findings suggest that D-tryptophan may influence neural plasticity and cognitive processes through modulation of NMDA receptor activity, glutamatergic neurotransmission, and neurotrophic factor release. Beyond cognitive domains, potential benefits may extend to behavioral and mood regulation, highlighting their multifaceted role in Central Nervous System (CNS) health[1].
