Enzyme
Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts are catalytic RNA molecules, called ribozymes. Enzymes' specificity comes from their unique three-dimensional structures. Like all catalysts, enzymes increase the reaction ra ...

Alkaloid
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.Chemical Encyclopedia: alkaloids xumuk.ru Alkaloids are produced by a large variety of organisms including , , Medicinal plant, plants, an ...

Sanguinaria Canadensis
''Sanguinaria canadensis'', bloodroot, is a perennial, herbaceous flowering plant native to eastern North America. It is the only species in the genus ''Sanguinaria'', included in the poppy family Papaveraceae, and is most closely related to ''Eomecon'' of eastern Asia. ''Sanguinaria canadensis'' is sometimes known as Canada puccoon, bloodwort, redroot, red puccoon, and black paste. Plants are variable in leaf and flower shape, and have been separated as a different subspecies due to these variable shapes, indicating a highly variable species. In bloodroot, the juice is red and poisonous. Products made from sanguinaria extracts, such as black salve, are escharotic and can cause permanent disfiguring scarring. Although preliminary studies have suggested that sanguinaria may have potential applications in cancer therapy, clinical studies are lacking, and its use is not recommended. Description Bloodroot grows from tall. It has one large basal leaf, up to across, with five t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanguinarine
Sanguinarine is a polycyclic quaternary alkaloid. It is extracted from some plants, including the bloodroot plant, from whose taxonomic name, ''Sanguinaria canadensis,'' its name is drawn; the Mexican prickly poppy (''Argemone mexicana''); ''Chelidonium majus;'' and '' Macleaya cordata.'' Toxicity Sanguinarine is a toxin that kills animal cells through its action on the Na+/K+-ATPase transmembrane protein. Epidemic dropsy is a disease that results from ingesting sanguinarine. If applied to the skin, sanguinarine may cause a massive scab of dead flesh where it killed the cells where it was applied, called an ''eschar''. For this reason, sanguinarine is termed an escharotic. It is said to be 2.5 times more toxic than dihydrosanguinarine. Alternative medicine Native Americans once used sanguinarine in the form of bloodroot as a medical remedy, believing it had curative properties as an emetic, respiratory aid, and for a variety of ailments. In Colonial America, sanguinarine fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eschscholzia Californica
''Eschscholzia californica'', the California poppy, golden poppy, California sunlight or cup of gold, is a species of flowering plant in the family Papaveraceae, native to the United States and Mexico. It is cultivated as an ornamental plant flowering in summer (spring in southern Australia), with showy cup-shaped flowers in brilliant shades of red, orange and yellow (occasionally pink and white). It is also used as food or a garnish. It became the official state flower of California in 1903. Description California Poppy is a perennial or annual plant growing to tall with alternately branching glaucous blue-green foliage. The leaves are alternately divided into round, lobed segments. The flowers are solitary on long stems, silky-textured, with four petals, each petal long and broad; flower color ranges through yellow, orange and red (with some pinks). Flowering occurs from February to September in the northern hemisphere (spring, summer, fall). The petals close at night ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
