Bio-catalysis in chemistry

This session contain bio-catalyst and function.  The main function of catalysts is to speed up reactions without becoming a part of the reaction products. Enzymes, the biological catalysts are highly specific, catalyzing a single chemical reaction or a very few closely related reactions. The exact structure of an enzyme and its active site determines the specificity of the enzyme. Substrate molecules bind themselves at the enzyme's active site. Substrates initially bind to the enzymes by non-covalent interactions, including hydrogen bonds, ionic bonds and hydrophobic interactions. Enzymes lower the activation energy and the reactions proceed toward equilibrium more rapidly than the uncatalyzed reactions. Both prokaryotic and eukaryotic cells commonly use allosteric regulation in responding to changes in conditions within the cells. Allosteric regulation can be positive or negative. Regulation by allosteric inhibitors is common in many biosynthetic pathways. A protective peptide in zymogens regulates by inactivating the protein.
