Aminoacids and derivatives

<p>Applications D-Cysteine is a strong inhibitor of Escherichia coli growth and also functions to provide inorganic sulfates for the sulfation of xenobiotics. D-Cysteine is a non-physiological isomer of L-Cysteine (C995000), and is not involved in protein or glutathione synthesis.<br>References Glazenburg, E., et al.: Biochem.

<p>Applications cis-9-Hexadecenoylcarnitine Inner Salt is an L-carnitine metobolite which are often used to diagnose specific inherited metabolic diseases.<br>References Yang, S. et l.: J. Chrom. B., Anal. Tech. Biomed. Life Sci., 857, 251 (2007); Minkler, P. et al.: J. Chrom. B., Anal. Tech. Biomed. Life Sci. 1061, 128 (2017);<br></p>

<p>Applications N-Acetyl-L-Tryptophan, is a derivative of L-Tryptophan (T947210), that can be used as competitive inhibitor to identify and characterize tryptophanases. It can also be used as an NK1 tachykinin receptor antagonist, that may help to develop a novel therapeutic intervention for the treatment of reperfusion injury in acute ischemic stroke.<br>References Turner, R. J., et al.: Neuroscience, 220, 1 (2012);<br></p>

<p>Applications A labelled imidazole, a versatile heterocycle used in the preparation of various biologically active compounds such as the amino acid histidine and is present in many antifungal medication. It is also used extensively as a corrosion inhibitor on transition metals such as copper.<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 Arispe, N. et al.: Biophys.
