CAS:<p>Acetyl-L-tyrosine amide is an analog of L-tyrosine that is used as an active substance in the field of uv absorption. Acetyl-L-tyrosine amide reacts with sodium hydroxide to form a soluble salt, which has been shown to have binding constants that are comparable to those of human serum. This compound also has fluorescence properties and can be used for the determination of neutral pH. The reaction products formed between acetyl-L-tyrosine amide and sodium hydroxide are hydrolyzed by acids and yield a molecule with rotameric properties. These rotameric properties can be modeled using a protein model without affecting the stability or function of the protein.</p>Fórmula:C11H14N2O3Pureza:Min. 95%Cor e Forma:PowderPeso molecular:222.24 g/mol(+/-)-Epicatechin
CAS:<p>(+/-)-Epicatechin is a phenolic compound found in many plants. It has been shown to have antioxidant properties and to protect cells from oxidative damage. Epicatechin has also been shown to have anti-inflammatory effects, which may be due to its ability to inhibit the production of inflammatory cytokines such as IL-1β and TNF-α. (+/-)-Epicatechin has also been shown to increase insulin sensitivity and enhance glucose uptake. The physiological effects of (+/-)-epicatechin are mediated through its binding with receptors on the surface of cells, including PPARs and GPR40, which stimulate the activity of enzymes involved in fat metabolism.</p>Fórmula:C15H14O6Pureza:Min. 95%Cor e Forma:PowderPeso molecular:290.27 g/mol5β-Pregnan-3α,6α-diol-20-one
CAS:Produto Controlado<p>5β-Pregnan-3α,6α-diol-20-one is an anticoagulant that inhibits the action of thrombin. It has been shown to inhibit the inflammatory response in a number of autoimmune diseases and inflammatory disorders. This drug also has a nitro group, which can be reduced to an hydroxyl group by reaction with sodium nitrite or other reducing agents. The antimicrobial properties of 5β-pregnan-3α,6α-diol-20-one are thought to be due to its ability to form particle aggregates with magnetic particles. These aggregates have an inhibitory effect on bacterial growth.</p>Fórmula:C21H34O3Pureza:Min. 95%Cor e Forma:PowderPeso molecular:334.49 g/mol
