Aminoacids and derivatives

<p>Applications Betaine, is the product of the enzyme oxidation of choline. It can also be used as an organic osmolytes. Betain is a methyl donor of increasingly recognized significance in biology. It can also be used for the treatment of homocystinuria which is an inherited disorder of the metabolism of amino acid methionine.<br>References J. Biol.

<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.

<p>Applications (S)-Carbidopa Methyl Ester N-cyclohexylideneis an impurity of Carbidopa (C175915), a prodrug inhibitor of aromatic amino acid decarboxylase.<br>References Sletzinger, M., et al.: J. Med. Chem., 6, 101 (1963)<br></p>

<p>Applications sn-Glycero-3-phosphocholine (Choline Alfoscerate) is a phospholipid; precursor in choline biosynthesis. sn-Glycero-3-phosphocholine is an intermediate in catabolic pathway of phosphatidylcholine. sn-Glycero-3-phosphocholine is used as an Nootropic.<br>References Schmidt, G., et al.: J.
