reactions involving enzymes

A large number of chemical reactions will be taking place in a cell. The rate and efficiency with which these reactions go on in a cell, depend on a group of macromolecules called enzymes. Enzymes are thus, biological catalysts. Enzymes are synthes..

Enzymes are the biocatalysts of life. They are defined as biocatalysts synthesized by living cells. They are simple or conjugate protein and specific in action. At present about 300 enzymes are recognized and classified into six classes by International Union of Biochemistry (IU..

Introduction - The reactions of amines are mainly due to participation of unshared pair of electrons of nitrogen which makes them react as a nucleophile or a base (A nucleophile is a species that attacks an electron - deficient carbon and a base is a species that attacks an electron defic..

If k 1 is very much less than k 2 that is k 1 << k 2 then the intermediate B is transformed into the product C as soon as it is forme..

Any chemical reaction requires a certain amount of energy to get initiated. This is called activation energy. Most of the molecules in a substrate have average kinetic energy, some have high energy and some have low energy. Under normal conditions of temperature only molecules with higher..

Enzymes are macromolecules, usually proteins, produced in living systems, which act as catalysts in physiological reactions. The striking characteristics of enzymes are their catalytic power and specificity. Enzymes have immense catalytic power; they ac..

Classification of Enzymes - Enzymes are generally classified on the basis of the type of reactions that they catalyse. 6 groups of enzymes can be recognised on this basis. The following table lists the 6 groups of enzymes along with example. fig. 14..

The different kinds of enzymes are named in different ways. Most often enzymes are named by adding a suffix 'ase' to the root word of the substrate. For example, Lipase (fat hydrolysing enzyme), Sucrase (breaking down sucrose). Sometimes the enzymes are named..

Dry distillation of the anhydrous alkali salts of acetic acid with soda-lime yields methane. ..
