D(+)-Tryptophan Chemical Properties,Uses,Production

Chemical Properties

white powder

Uses

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

Definition

ChEBI: The D-enantiomer of tryptophan.

General Description

White solid.

Air & Water Reactions

Slightly soluble in water.

Reactivity Profile

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.

Fire Hazard

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