The Importance of Isoenzymes Examples of Isoenzymes Lesson SummaryIsozymes and Isoenzymes Enzymes are a category of proteins that speed up biochemical reactions. They are ubiquitous and found in all living organisms. Without enzymes functioning as biological catalysts, biochemical reactions would take so...
Enzymes are chemical catalysts in the body. Their main function is to assist in the break down of larger molecules into smaller substances that can be utilized. What do enzymes do? Simply put, enzymes break down larger molecules into smaller molecules. For instance, they may break down polysacc...
Chemical synthesis plays a key role in pharmaceutical research and development. Campos et al. review some of the advantages that have come from recent innovations in synthetic methods. In particular, they highlight small-molecule catalysts stimulated by visible light, enzymes engineered for versatility ...
The reason for this is still not clear, but may be due to weak activity of the enzymes associated with hispidin biosynthesis. Although biosynthesis of dimeric hispidins from two monomers via oxidative coupling by lignolytic enzymes, laccase and peroxidase, has been proposed, the details of this ...
remain sequestrated by the enzyme and are not released in solution before reacting with tRNA. The importance of this process can be appreciated by considering that the set of aaRS enzymes, responsible for the association of amino acids with their cognate tRNAs, actually holds the key of the gen...
Introduction Human cytochrome P450 enzymes (P450s) are known as versatile biological catalysts with remarkably broad substrate specificity [1–14]. A variety of different drugs are metabolized by only a few P450 isozymes, mainly by CYP2B6, CYP2C9, CYP2C19, CYP2D6, and CYP3A4 [15]. ...
Enzymesare largeproteinmolecules that act as biologicalcatalysts, accelerating chemical reactions without being consumed to any appreciable extent themselves. The activity of enzymes is specific for a certain set of chemical substrates, and it is dependent on both pH and temperature. ...

Moreover, thiourea moiety has been incorporated in many tyrosine kinase inhibitors due to its ability in the formation of hydrogen bonds in the ATP binding cavity of enzymes [33]. For instance, the thiourea derivative YH345A has shown strong protein farnesyl transferase inhibition activity [4]. ...
In the stomach, it is subjected to the action of digestive enzymes, gastric acid, and the mechanical movements of the stomach. These factors will also contribute to its release from the food matrix. Lycopene can be incorporated into lipid droplets and pass into the small intestine. There, the...
