The lab we conducted involved a process called the Maillard Reaction. When it comes to cooking meats, heating the food causes the proteins, especially those nearest the surface of the meat, to denature. These denatured proteins become more chemically reactive to other molecules in their environment. One of the primary reactions that occur when browning meats and many other foods is called the Maillard Reaction. The Maillard Reaction is a non-enzymatic chemical reaction between amino acids and…

Metal electrodeposition is the process of reduction reaction and crystallization of metal ions in an electrolytic cell according to the mechanism of electrolysis. Electrodeposition is one of the main methods for improving and enhancing the metal substrate property. Now, in order to overcome the defect of single electrodeposition with shortcomings of cracks, pores, pits, pocking and so on, the modern new techniques sprang up such as jet electrodeposition [1], ultrasonic vibration assisted…

MSA University, faculty of pharmacy, Bio chemistry department. Course code PB301 Nucleotides Student name: ID: Under supervision of DR: Teaching assistant Structure Nucleic acids are polymers consist of units called nucleotides. These mononucleotide units react together by intermolecular dehydration reactions that create phosphate ester bonds. Those reactions are either, catalyzed or specialized enzymes. The nucleotide units are created by smaller types of components. Each nucleotide…

Carbonyl compounds undergo various types of reaction. In these reaction the carbonyl carbon or carbonyl oxygen is prone to attack generally by a nucleophile. Different types of carbonyl compounds undergo different types of reactions and the mechanisms of them are also different. The products or by-products or intermediate products of these reactions are very much useful in laboratory synthesis, industry etc. here we will discuss some very much important reactions which are very important for…

They offer the specificity required to separate similar compounds from each other, such as separating polymers in plastic waste streams. Batteries:- They can replace water as an electrolyte in batteries. They are prefer because of their low vapor pressure. Their minimum electrochemical capacity is 6 volts as compared to water which is 1.23 volts. Ionic…

Diaper Debate When my wife and I were expecting, we made a list of all the items that should be purchased before the baby arrived. The one item every one of our friends and relatives said we could not have enough of was diapers. We started early on by pricing plain, standard, and no frills disposable diapers. These were the diapers I knew and assumed were the only option for an on-the-go family like ours. I slowly noticed other families with new babies and trends among them. Not all babies…

Synthesis ofp-[1-(p-Hydroxyphenyl)-1-(p-Methoxyphenyl)Ethyl]Phenol (HMEP) 0.2 mol of phenol was mixed with the solution containing 100 mL of acetic acid in 200 mL of concentrated hydrochloric acid in 500 mL five necked round bottom flask fitted with anoil bath, thermometer, mechanical stirrer, reflux condenser. The contents of the flask was stirred for a period of 15 min, the solution was heated to 65oC, 0.1 mol ofp-methoxyacetophenone was introduced into a dropwise to the solution for about 6 h…

“Chemical engineering is a branch of engineering that applies physical sciences (e.g. chemistry and physics) and life sciences (e.g. biology, microbiology and biochemistry) together with mathematics and economics to produce, transform, transport, and properly use chemicals, materials and energy (Cohen, 1996).” The field of chemical engineering is very diverse, covering areas from biotechnology to mineral processing. It would take too long to list all the products that are impacted by chemical…

Destin Briggs Lu Jack Chem 4235 11/4/2017 Original Synthesis of Cadmium Nitrate Tetra-Hydrate Cadmium nitrate tetra-Hydrate is an inorganic compound from the family of compounds with the general formula Cd (NO3)2.XH20, where X=4, hence the molecule has four molecules of water of crystallization in its structure. It exists as a salt but in its anhydrous state, it is known to be a volatile substance. It is a colorless substance as are all the compounds in the family of cadmium nitrates. Cadmium…

perspectives. Non-covalent or covalent functionalization of CNTs can enhance their compatibility and solubility. The non-covalent functionalization of CNTs includes non-covalent coating with surfactants, surface wrapping with long polymer chains, non-covalent adsorption of non-charged polymer chains, etc. the advantage of non-covalent functionalization is that the structure and original properties of CNTs are not changed after modification14. Non-covalent approaches utilize π-stacking or van der…
