Polymer - A word, which is connote for large molecules (that a molecule made from simple repeating units called monomers). The monomers are main building block of polymers. Polymers play an essential and ubiquitous role in everyday human life because of the extraordinary range of properties. Polymers are among the most widely used and important type of materials today. Polymers have been with us from the beginning of time; they form the very basis (building blocks) of life. Animals, plants all…

anhydride show the peak at δ=125−135 ppm.13, 32 Moreover; carbon attached to the oxygen atom directly show the peak in the region of δ =30−70 ppm. The peaks at δ = 0−35 ppm correspond to methyl and methylene carbon, unsaturated carbon atom of fatty acid alkyl chain in the HBA show the peak at δ = 127 ppm. The 13C NMR spectra of HBA-BMF show the similar peaks as HBA with two additional peaks around δ = 180 ppm and δ = 90 ppm attributed to the carbon atoms of the symmetrical s-triazine ring and…

Case study 4 Even in the absence of a known drug target, a drug can be designed to perform a specific function through the testing of a variety of substituents. Through this, the biological activity of each substituent can be determined in order to create the final product in the form of a marketable drug. An example of this is oxamniquine, which is a drug that is active against schistosomes, the causative agent for schistosomiasis (Patrick, 2013, p. 305). Schistosomiasis, caused by three…

cm-1 range showed compound with characteristic absorption bands at 3432 cm-1 for alkyne group, 1614 cm-1 for olefin and 1513 cm-1 for arene , 1240 cm-1 for alcohol and phenol, 1159 and 1112 cm-1 for ether group, 1448 cm-1 for alkanes, 567 cm-1 for alkyl bromide which were closely similar to Catechin. No other visible peaks were observed in the spectra which indicate that a simple soxhlet extraction itself yields Catechin with fewer…

Introduction Since the beginning of the 21st century, Australia has become one of the highest greenhouse gas producers per capita amongst the world. With a vast growth in the Australian population, the demand for burning fuel in motor vehicles has led to an increased amount of greenhouse gases being released into the atmosphere, contributing over 16 % to the Australia’s total greenhouse emission. It has become a necessity for the Australian government to find alternative sources of fuel to cope…

Like most Mary Kay beauty products, the Mary Kay mineral eye shadow features colors that are hand-selected by a professional makeup artist.

With a mineral formula that uses natural ingredients, you can sparkle anytime of day or night when you use this eye color collection. This fade-resistant, lightweight eye shadow still looks good even hours after the first application thanks to its…

They are formed when an oxygen atom bound to an alkyl group replaces the hydroxyl group in the carboxylic acid. Esters can be formed through a process known as esterification, which starts with a carboxylic acid and an alcohol. The carbonyl carbon in the carboxylic acid acts as an electrophile and the…

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…

separate medicines. In relation to the seed/kernel (Bai Guo), G. biloba has a range of active ingredients such as Bilobol, Ginkgolic Acid and Hydroginkgolic Acid. Out of these three compounds Bilobol is probably the most potent. Bilobol is an alkyl resorcinol. Alkyl resorcinols are variants of phenolic lipids that contain a large number of aliphatic chains and phenolic rings. If bilobol is used incorrectly it can become a rampant irritant, especially affecting the skin and other epithelial…

involve a 2-step substitution mechanism where substituents are attached to aromatic rings. Two types of this reaction include alkylation and acylation. Alkylation involves the synthesis of alkylated products from reactions between aromatic rings and alkyl halides or alkenes. During this reaction the presence of a strong Lewis…
