Enzymes are potent catalysts. The enormous catalytic activity of enzymes can perhaps best be expressed by a constant, k cat, that is variously referred to as the turnover rate, turnover frequency or turnover number.This constant represents the number of substrate molecules that can be converted to product by a single enzyme molecule per unit time (usually per minute or per second).

Enzymes are protein catalysts that lower the energy barrier for a reaction and speed the rate of a chemical change. The kinetics of reactions catalyzed by enzymes, as well as several mechanisms underlying the kinetics, have been comprehensively studied and written in textbooks (1, 2). The importance of quantitative evaluation of enzymatic ...Figure 1: Chemical formula of a reaction using the enzyme ADH and beneath it a structure of alcohol dehydrogenase ADH1B*1 (from PDB entry 1HSZ).

Alcohol Dehydrogenase (ADH) is the enzyme that catalyzes the first step in the metabolism of alcohol in humans. ADH catalyzes the oxidation of a broad range of substrates containing hydroxyl groups, including ethanol. In the case of ethanol, the alcohol is converted into acetaldehyde, another toxic compound, which is then metabolized further. 92 A. Rogers and Y. Gibon.

By providing an alternative reaction with a lower activation energy, they allow the reaction to proceed at a much higher rate. It is important to note that enzymes do not change the equilibria of a reaction; they can only increase the rate. Without the enzyme, the reaction would therefore still proceed in ...

Enzymatic time-temperature indicators (TTIs) usually suffer from instability and inefficiency in practical use as food quality indicator during storage. The aim of this study was to address the aforementioned problem by immobilizing laccase on electrospun chitosan fibers to increase the stability and minimize the usage of laccase. The addition of NaN3, as and enzyme inhibitor, was intended ...

A substrate is a molecule upon which an enzyme acts. If we think of the enzyme as a machine in an assembly line, the substrate would be what we put into the machine to get the output we want. The substrate for alcohol dehydrogenase (ADH), the enzyme we are working within this case, is ethanol; however, ADH can also bind other substrates with a ...
