Bromelin
Bromelain is an enzyme extract derived from the plant stem, stems of pineapples, although it exists in all parts of the fresh pineapple. The extract has a history of folk medicine use. As an ingredient, it is used in cosmetics, as a topical medication, and as a meat tenderizer. The term "bromelain" may refer to either of two protease enzymes extracted from the plants of the family Bromeliaceae, or it may refer to a combination of those enzymes along with other compounds produced in an extract. Bromelain enzymes are called ''fruit bromelain'' and ''stem bromelain''. Although tested in a variety of folk medicine and research models for its possible efficacy against diseases, bromelain has only one approved clinical significance, clinical application issued in 2012 by the European Medicines Agency a topical medication called ''NexoBrid'', used to remove dead tissue in severe skin burns. Extract components Bromelain extract is a mixture of protein-digesting (proteolysis, proteolyti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruit Bromelain
Fruit bromelain (, ''juice bromelain'', ''ananase'', ''Bromelase'' (a trademark), ''bromelin'', ''extranase'', ''pinase'', ''pineapple enzyme'', ''traumanase'', ''fruit bromelain FA2'') is an enzyme. This enzyme catalysis, catalyses the following chemical reaction : Hydrolysis of proteins with broad specificity for peptide bonds. Bz-Phe-Val-Arg-NHMec is a good synthetic substrate This enzyme is isolated from pineapple plant, ''Ananas comosus''.

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 ...

Stem Bromelain
Stem bromelain (SBM) ( EC 3.4.22.32), a proteolytic enzyme, is a widely accepted phytotherapeutical drug member of the bromelain family of proteolytic enzymes obtained from ''Ananas comosus''. Some of the therapeutic uses of SBM are reversible inhibition of platelet aggregation, angina pectoris Angina, also known as angina pectoris, is chest pain or pressure, usually caused by insufficient blood flow to the heart muscle (myocardium). It is most commonly a symptom of coronary artery disease. Angina is typically the result of obstru ..., bronchitis, sinusitis, surgical traumas, thrombophlebitis, pyelonephritis and enhanced Absorption (pharmacokinetics), absorption of drugs, particularly of antibiotics. Its anti-metastasis and anti-inflammatory activities are apparently independent of its proteolytic activity. Although poorly understood, the diverse Pleiotrophy, pleiotrophic effects of SBM seem to depend on its ability to traverse the membrane barrier, a very unusual propert ...
