What Is a Catalyst in Chemistry?
What Is a Catalyst in Chemistry?A catalyst is a substance that can be used to alter the reactions of chemical reactions. In chemistry, it is often associated with the reactants and their reaction with the products.Depending on the catalytic properties of the substance, it can either act as a 'gate' to allow a more favorable reaction to take place or as a catalyst to stop the other reactions before they happen. In addition, it can also act as a 'bridge' between the two reactants or produce an intermediate that has catalytic properties, making it possible to take advantage of the different properties of both reactants. Catalyst can be separated into two categories - one that acts as a 'conduit' (to connect one end of the chain with the other) and another that act as a 'reactor'.The second category of the catalyst is also known as a chelator and works like a poison to remove toxic substances from the bloodstream and body function. Usually, it is paired with a first type of catalyst that does not act as a 'conduit' but rather as a 'gate'.In medicine, the use of medicines that reduce the toxicity of the body functions can be used to treat many diseases. Medicines with antineoplastic activity and the ability to kill tumor cells have been especially effective in this regard. Chemotherapy medicines, which are medicines that have antineoplastic and immunomodulatory properties, are also effective.For instance, chemotherapy drugs such as methotrexate, doxorubicin, and arecopropene have antineoplastic activity. These drugs cause the death of cancer cells, either by killing the cells directly or by altering the environment of the body to make them die.Similarly, antitumor agents such as doxorubicin, hydroxychloroquine, and paclitaxel can cause tumor cell death by disrupting the cell cycle. Moreover, since the mechanism of action of chemotherapy drugs is to make the tumor cells die, there is a possibility that treatment with chemotherapy may have serious side effects such as blood loss, heart attack, or stroke.Chemotherapeutic agents interfere with free radicals produced by the cellular metabolism that are responsible for the oxidation of oxygen molecules in the cellular DNA. It is thus important to find out if the cancer is a non-metastatic form of the disease, and this will help in choosing the right chemotherapeutic agent and consequently the right course of treatment.
