<p>Applications Labelled analogue of L-Vailne. L-Valine is an essential amino acid and one of 20 proteinogenic amino acids. L-Valine cannot be manufactured by the body and must be acquired through diet or supplementation. L-valine is found in grains, dairy products, mushrooms, meats, peanuts and soy proteins. L-Valine has been used in studies to attenuate arrhythmias and induce hypotensive effects.<br>References Choi, C.W. et al.: Anim. Feed Sci.

<p>Applications Poly(ethylene Glycol) molecules of an average molecular mass of 200. Poly(ethylene Glycol) is used in various applications from industrial chemistry to biological chemistry. Recent research has shown PEG maintains the ability to aid the spinal cord injury recovery process, helping the nerve impulse conduction process in animals. In rats, it has been shown to aid in the repair of severed sciatic axons, helping with nerve damage recovery. It is industrially produced as a lubricating substance for various surfaces to reduce friction. PEG is also used in the preparation of vesicle transport systems in with application towards diagnostic procedures or drug delivery methods.<br>References Borgens, R. et al.: J. Neurosci.

<p>Applications D-Glutamic acid 1-tert-butyl ester is a protected form of D-Glutamic acid (G596965). D-Glutamic acid is an unnatural isomer of L-Glutamic acid (G596960), and is found in bacterial cell wall peptidoglycan of gram-positive and gram-negative bacteria. D-Glutamic acid also occurs as poly-gamma-Glutamic acid, which is a weak immunogen but is capable of acting as a hapten (a small molecule that induces the production of antibodies, as well as binding to them).<br>References Dougherty, T., et al.: J.
