<p>Stability Hygroscopic<br>Applications Indole-3-carboxaldehyde- 13C8 is the labelled Indole-3-carboxaldehyde (I615020) which is a tryptophan (T947200) metabolite from Streptomyces staurosporeus and it is chemical constituent from Inula wissmanniana. Indole-3-carboxaldehyde and other tryptophan metabolites play an important role in mammalian gut immune homeostasis.<br>References Yang, S., et al.: J. Nat.

<p>Stability Hygroscopic<br>Applications L-Glutamic Acid, Magnesium Salt Hydrobromide is an metabolite of L-Glutamic acid, a non-essential amino acid. Its salt form (glutamate) is an important neurotransmitter that plays a key role in long-term potentiation and is important for learning and memory. It is also a key molecule in cellular metabolism. L-Glutamic Acid, Magnesium Salt Hydrobromide has also been investigated for sedative properties as a tranquilizer.<br>References McEntee, W., et al.: Psychopharmacology, 111, 391 (1993), Manev, H., et al.: Mol.

<p>Applications L-Glutamine-2,3,3,4,4-d5 is the isotope labelled analog of L-Glutamine (G597000); an essential amino acid that is a crucial component of culture media that serves as a major energy source for cells in culture. L-Glutamine is very stable as a dry powder and as a frozen solution. In liquid media or stock solutions, however, L-glutamine degrades relatively rapidly. Optimal cell performance usually requires supplementation of the media with L-glutamine prior to use.<br>References Rivett, A., et al.: J. Biol.
