<p>Applications L-Citrulline-d7, is the labeled analogue of L-Citrulline (C535700), which is an amino acid, first isolated from the juice of watermelon, Citrullus vulgaris Schrad., Cucurbitaceae. It is also used in the treatment of asthenia.<br>References Kurtz, et al.: J. Biol. Chem., 122, 477 (1938), Rajantie, J., et al.: J. Pediatr., 97, 927 (1980), Carpenter, T.O., et al.: N. Engl. J.

<p>N-Acetyl-L-alanine is the N-acetylated form of L-alanine and is a nonessential amino acid. It is an amide containing one nitrogen atom and two carbonyl groups. The nitrogen can be found in either the alpha or beta position on the amide. The biological properties of N-acetyl-L-alanine are similar to those of L-alanine, as it is used as a substrate for protein synthesis and has been shown to inhibit p21 and epidermal growth factor. The conformational properties of N-acetyl-L-alanine are different from that of L-alanine due to its changed shape, which may affect its biological activity.</p>

<p>DL-Proline is a biological molecule that has been shown to bind to the DNA binding domains of proteins. This binding can be seen with the crystal structures of DL-proline and protein. The reaction mechanism for DL-proline is as follows:<br><br>DL-Proline + Protein → Proline + Protein<br><br>The equilibrium constant for this reaction is 1.0 at 298 K. The pKa value for the amide group in DL-proline is 4.8, which means that it will react with water and form an amine group at physiological pH levels. DL-Proline has been shown to have metabolic disorders.</p>

<p>7-[5-(Fluoro-methyl-phosphoryl)oxypentyl]-4-nitro-2,1,3-benzoxadiazole is a reactivator of the central nervous system. It is a noncompetitive antagonist at muscarinic receptors and blocks postsynaptic acetylcholine release from cholinergic neurons. It has been shown to have no effect on blood pressure but does cause an increase in locomotor activity in animals. This drug binds to the hippocampal formation and the ventral hippocampus, which are areas of the brain that are involved in memory and spatial navigation. The distribution of this drug postulated to be due to its ability to penetrate micron sized openings in cell membranes.</p>

<p>(Fluoro-Methylphosphoryl)Oxycyclohexane is an organophosphorus compound that acts as a nerve agent. It inhibits the enzyme acetylcholinesterase, which is responsible for breaking down acetylcholine, leading to excess cholinergic stimulation. This can cause excessive contraction of muscles or even death. The exposure to (Fluoro-Methylphosphoryl)Oxycyclohexane can be detected by analytical methods such as gas chromatography/mass spectrometry. Oximes are used in the reactivation of acetylcholinesterase and are effective in preventing neuronal death. They bind to the phosphonyl group in (Fluoro-Methylphosphoryl)Oxycyclohexane and prevent it from inhibiting the enzyme acetylcholinesterase.</p>

<p>2-Phenyl-2-(2-piperidyl)acetamide is an enantiomeric amide that can be used as a chiral building block for the synthesis of other organic compounds. It is synthesized by reacting phenylacetic acid with piperidine. 2-Phenyl-2-(2-piperidyl)acetamide is a primary amide and has been shown to have analgesic properties.</p>
