- Q:What is the chemical nature of the enzyme?
- Enzyme is an amphoteric electrolyte, soluble in water, easy to precipitate at the isoelectric point, the enzyme activity-pH curve and the zwitterion of the enzyme. The enzyme is a high-molecular colloidal material, generally can not pass through the semipermeable membrane; Dissociation curve similar to the enzyme in the electric field can be the same as other proteins swimming; ③ lead to protein denaturation factors, such as ultraviolet, heat, surfactant, heavy metals, protein precipitants, etc., can make the enzyme failure; Protease hydrolysis and loss of activity.In addition, the most direct evidence is that all has been highly purified and crystallized enzyme for a primary structure analysis, the results indicate that the enzyme is a protein.
- Q:Where are they good catalysts and why?? THanks!
- A catalyst is a substance that speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy. Catalysts appear not to take part in the reaction. Frequently, catalysts are not very reactive. Acids and bases, on the other hand, are very reactive. Acids (as H+) and bases ( as OH-) sometimes function as catalysts in some organic reactions. They appear to be catalysts because in the course of the mechanism H+ or OH- is regenerated.
- Q:Can chemical reaction limits be changed by catalyst or other methods?
- You can use heating, pressurization and other methods.
- Q:Can the catalyst be a reactant in chemistry?
- There is also a saying that the catalyst participates in the chemical reaction. In a general chemical reaction, the effect of the catalyst is to reduce the activation energy required for the reaction to occur, essentially to turn a more difficult reaction into two, In the second reaction, the catalyst in the first reaction plays the role of the reactant, and the catalyst in the second reaction plays the role of the product, so that the catalyst is not present before and after the reaction Variety.
- Q:Manganese dioxide can be used as a catalyst for various chemical reactions
- The reactor may be a reactant,
- Q:The beginning of the chemistry plus the catalyst and the plot without the Cuihua agent
- What image, rate or balance?
- Q:Like biological and industrial reations. Thanks.
- Reactions that have high Activation Energy need catalysts to speed up reactions. These reactions aren't spontaneous since the reactants do not have enough energy to overcome the activation energy barrier. Catalysts are compounds that speed up reactions by providing an alternative pathway for the reaction. It is a common misconception that catalysts lower the activation energy. It doesn't actually lower the activation energy, instead it provides an alternative pathway with lower activation energy. For example, breakdown of hydrogen peroxide happens in nature but, relatively slowly. When you add a little bit of manganese dioxide, the breakdown happens a lot faster. Another example is, breakdown of glucose in the body. It is facilitated by an enzyme called amylase (or carbohydrase). An industrial example is the use of vanadium pentoxide (V2O5) in the Contact process, where SO2 is converted to SO3 in the presence of V2O5. Hope that helps!
