<p>H-Tyr-Tyr-Phe-OH acetate salt is a reaction product of the matrix-assisted laser desorption ionization (MALDI) technique. It is an analog of tyrosine, with a hydroxyl group substituted for the amino group. The protonation state of this molecule has been determined by the hydration constant and the centroid to be a neutral pH. Using hydrogen bonding, H-Tyr-Tyr-Phe-OH acetate salt binds to the mitochondria in cells, which may lead to a higher rate of reaction.</p>

<p>Fmoc-Lys-OH·HCl is an acidic pyrylium that has been shown to be a potent inhibitor of tumor vasculature. It binds to the human serum albumin and inhibits the binding of ligands to the receptor tyrosine kinases, which are involved in brain tumor proliferation. Fmoc-Lys-OH·HCl has also been shown to inhibit the growth of cancer cells by binding to cell membrane receptors and inhibiting protein synthesis. This compound is also isomeric, meaning it can exist in different forms with different properties.</p>

<p>Fmoc-Leu-Gly-OH is a dipeptide that is reversibly soluble in water and organic solvents. It has been found to be stable at millimeter and nanometer scales, which makes it suitable for use as a hydrogel or fiber. Fmoc-Leu-Gly-OH has also been shown to form membranes of variable thickness (from micrometers to nanometers) that are sensitive to pH changes. This means that the membrane can be used for sensing pH levels in a variety of environments. Dipeptides are amphiphiles, meaning they have both hydrophilic and lipophilic properties. This makes them useful for forming self-assembled structures, such as hydrogels and membranes, that are capable of transporting water molecules through the structure.</p>

<p>A component of snake venom, this product contains disulfide bonds between Cys1 and Cys15/Cys3 and Cys11. <br>Due to their structural and functional homology to the endothelin peptides, Sarafotoxins can enhance vasoconstriction through stimulating the class A G-protein-coupled, endothelin ETA and ETB receptors. This in turn leads to left ventricular dysfunction and bronchoconstriction.</p>

<p>IL-8 Inhibitor Ac-Arg-Arg-Trp-Trp-Cys-Arg-NH2 is a molecule that blocks the receptor for IL-8, a c-c chemokine.

<p>H-Gly-Gly-His-Ala-OH is a peptide of four amino acids. It has been shown experimentally that the side chain of His is always oriented in the same direction, regardless of the conformation. The proton shift constants and vicinal coupling constants for Gly, Gly and Ala are constant, while His has a variable proton shift constant. The experimental parameters for the molecule have been rationalized by using conformational shifts to explain their variability. For example, the proton shift constants have been found to be dependent on the rotation about an axis perpendicular to the peptide backbone. H-Ala-Gly-Gly-His-OH is a pentapeptide with five amino acids that differs from HGGHAOH by having Ala instead of His at position 1. The vicinal coupling constants are different and so are other experimental parameters.</p>

<p>Glutamine is a non-essential amino acid that is found in the cell in large amounts. It functions as a precursor of glutamate, an important neurotransmitter and intermediate in protein synthesis. Glutamine also has antioxidant properties, which may be due to its ability to donate hydrogen atoms or act as a reducing agent.

The uptake of glutamine is rapid at low concentrations, but becomes slower at higher concentrations. Glutamine is catabolized by the liver and kidney into glutamate and ammonia.<br>Glutamate dehydrogenase (GLDH) catalyzes the conversion of glutamate to α-ketoglutarate, producing NADH and H+.<br>The genetic mechanisms underlying the synthesis of glutamine are not well understood; however, one hypothesis states that glutamine could be synthesized from alpha-ketoglutarate via the reverse transamination reaction during periods when glucose</p>

<p>Vasopressin is a peptide hormone that regulates water balance. It is synthesized in the hypothalamus and stored in the posterior pituitary gland, from where it is released when blood pressure falls. Vasopressin binds to V1 receptors in the kidney and vascular smooth muscle cells, causing vasoconstriction and increased blood pressure. Vasopressin also stimulates phosphatidic acid synthesis and hypotension, which are mediated through V2 receptors. Vasopressin has been found to be effective against cardiac arrest and myocardial infarction in animals. This drug has also been shown to stimulate the paraventricular nucleus of the hypothalamus and inhibit sympathetic activity in ganglia.</p>
