DescriptionECHEMI Editorial Referencewhite powderChEBI: The D-enantiomer of tryptophan.D(+)-tryptophan is the D-form (non-proteinogenic form) of the amino acid tryptophan. It can be used for Human embryonic kidney cell (HEK-293, ATCC: CRL-1573) culture. It is also a sweetener used to study the release of incretins from enteroendocrine cells triggered by sugar but not by sweeteners. D-tryptophan (Full name D (+)-Tryptophan) is a white to pale yellow or white crystalline powder at room temperature, odorless or slight odor, sligh

D(+)-tryptophan is a white solid. (NTP, 1992)|D-tryptophan is the D-enantiomer of tryptophan. It has a role as a bacterial metabolite. It is a tryptophan and a D-alpha-amino acid. It is a conjugate base of a D-tryptophanium. It is a conjugate acid of a D-tryptophanate. It is an enantiomer of a L-tryptophan. It is a tautomer of a D-tryptophan zwitterion.|Tryptophan is one of the 20 standard amino acids, as well as an essential amino acid in the human diet. It is encoded in the standard genetic code as the codon UGG. The D-stereoisomer is occasionally found in naturally produced peptides (for example, the marine venom peptide contryphan). The distinguishing structural characteristic of tryptophan is that it contains an indole functional group. It is an essential amino acid as defined by its growth effects on rats.CertificatesBasic Info-

Air and Water Reactions:Slightly soluble in water.
Reactive Group:Salts, Acidic
Reactivity Profile:Acidic salts, such as D(+)-TRYPTOPHAN, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
