<p>Applications 2-Hydroxy L-Tryptophan is a metabolic intermediate in the biosynthesis of the neurotransmitters serotonin and melatonin from Tryptophan.<br>References Southan, M.D., et al.: Med. Chem. Res., 6, 343 (1996);<br></p>

<p>Applications Epi-Lacosamide is an impurity of Lacosamide (L098500), a medication used for the adjunctive treatment of partial-onset seizures and diabetic neuropathic pain. Lacosamide is a potent anticonvulsant.<br> Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package<br>References Choi, D., et al.: J. Med. Chem., 39, 1907 (1996), Morieux, P., et al.: Bioorg. Med. Chem., 16, 8968 (2008),<br></p>

<p>Applications Used for the counterselection of TRP1, a commonly used genetic marker in the yeast Saccharoyces Cerevisiae. An antimetabolite for the tryptophan pathway in yeast, and is toxic by virtue of its antimetabolite conversion to 5-Fluorotryptophan. It can be used for the selection of tryptophan auxotroophs.<br>References Toyn, J.H., et al.: Yeast, 16, 553, 560 (2000)<br></p>

<p>Stability Hygroscopic, moisture sensitive<br>Applications Stearoyl L-α-Lysolecithin is an bioactive lysophosphatidylcholine derived compound found to be released by bronchial epithelial cells. Stearoyl L-α-Lysolecithin have also been utilized in the development of liposomes and michelles by drug transdermal delivery devices.<br>References Zhuge, Y., et al.: Allergy Asthma Immunol Res., 6, 66 (2014)<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.

<p>Stability Hygroscopic<br>Applications L-Carnitine-d3 Chloride is the isotope labelled analog of L-Carnitine (C184110); a vitamin (enzyme cofactor). It is an essential cofactor of fatty acid metabolism and is required for the transport of fatty acids through the inner mitochondrial membrane. Synthetized primarily in the liver and kidney with the highest concentrations found in heart and skeletal muscle. Dietary sources include red meat, dairy products, beans, avocado.<br>References Mitchell, M.E., et al.: Am. J. Clin. Nutr., 31, 293 (1978); Lango, R., et al.: Cardiovasc.
