Redox

the roots of horseradish) is a member of a large family of enzymes known as peroxidases; hemoproteins that can catalyze one-electron oxidation of a substrate in the presence of peroxide. It is largely an alpha-helical protein which binds heme as a redox cofactor. The “heme nitrovinyl” group is specifically where nitrite modification of the heme macrocyle occurs in HRP, in the presence or absence of hydrogen peroxide. It’s regioselective at the 4-vinyl group leading to the formation of the heme…

In theory, we can look at the asteroid as one giant particle with a static electric charge. As our asteroid moves rapidly through the air, it now becomes a moving charge. Once it becomes a moving charge, it should be capable of producing a magnetic field, as it produces its own current by moving through the air. The exact magnitude of the field will depend on the speed and charge of the asteroid, which will likely vary at any moment. The fragment entering the earth’s atmosphere is heated to a…

Antibiotics are the most important group of drugs which play a significant role to protect humans and animals against bacterial infections (3). In other words, the use of antibiotics is the most conventional method for treating humans (4). These drugs also are used in fish farming industries in order to improve growth (5). Antibiotics are naturally absorbed by the human body after the use. Therefore, much of the drugs or their metabolites are removed from the body through the urine and feces…

different molecules since the Carbons in the Lipids have a higher oxidation number, which leads to a higher energy density than the lower oxidation numbers of Carbohydrates(2). The energy density of Lipids versus Carbohydrates ultimately boils down to Redox Reactions and the movement of electrons in reduction and oxidation reactions between organic molecules. For example, the ten Carbon atoms which are connected to two Hydrogens and two Carbons in the large Lipid chain for the molecule known…

Regeneration of enzymatic cofactors is the most limiting technical challenge of employing biochemical synthetic reactions for industrial chemical manufacturing. Consequently, requirement and the high cost of these cofactors has limited, isolated biocatalysts for production of fine chemicals. We strived to engineer a drop-in, cofactor regeneration technology, circumventing limited use of isolated biocatalyst for consumer chemicals. Presented here is a biologically engineered artificial organelle…

Standard solution is the solution that is been made by dissolving a precise mass of reactant meaning the starting substance in a chemical reaction, and it is important that the mass is weighed accurately into distinguish volume of water that will be used. This tells us that if the concentration of standard solution is accurate then it can also be used to work the concentration of a different solution that it can also react with. Its concentration is generally given in mol dm-3. Standard solution…

school complimented the skills that I developed throughout my placement at the Honeywell Plant. Aiding chemists in the laboratory, I brought the lab skills that I have developed throughout A-Level chemistry and actively demonstrated my knowledge of redox and organic chemistry. Working alongside engineers on plant projects, I witnessed how the knowledge of mechanics is essential in the field of engineering and that mathematics is one of the greatest tools any engineer can possess. These…

2.2.3 Definition of Chelating Ligand EDTA From the above discussion, it can be concluded that chelating ligand EDTA is a process of reversible bond formation of a ligand that serves as chelating ( chelting agent or Chelator) that exist within the compound of EDTA. Basically, EDTA combines with some specific ion, so it causes the functions of EDTA as chelator. When the functions of EDTA as chelator, EDTA is a liquid ( solution) 2.3 Volcanic Ash Volcanic ash or sand is volcanic material debris…

gravity type filtration systems, the filter medium can be mechanically or chemically driven to remove contaminates. The most common methods of contaminate removal for filtration medium mechanically remove large particulates, adsorption, absorption and redox or chemical reactions to produce safe drinking water2. Porous filter medium allows more medium surface area to interact with contaminates in the water as well as to create smaller pathways to mechanically remove particulates within the…

Data). This suggests the impairment of antioxidant defense system. DJ-1 is a chaperone-like protein localized in the mitochondria, cytoplasm and nucleus and protects cells from oxidative stress via scavenging ROS (6). DJ-1 also serves as a sensor of redox status (6). DJ-1 with irreversible oxidation of cysteine at position 106 (Cys-106) to sulfonic acid losses its cytoprotective…
