Adenosine Triphosphate (ATP) is the body’s main source of chemical energy. It is produced by breaking down nutrients such as glucose, fatty acids and proteins, which are all found in food. At the start of the race, anaerobic pathways are used to provide a quick source of energy. Most of this energy is derived from the catabolism of fats. Since lipids are more reduced than carbohydrates, they are capable of storing more energy per unit weight. Triacylglycerols are the lipids used for energy…

must be selected. (f) Thin layer chromatography is performed to assess the purity of the recrystallized product. (g) Melting point determination is performed in order to assess the purity of the recrystallized product. Benzanilide, C13H11NO has a carbonyl group so placed as to make the compound a ketone along with a secondary amine group in between two aromatic benzene rings. This chemical composition give the molecule certain characteristics of both the non-polar and polar compounds.…

of acid solution opens the tube caps and forms carboxylic groups at the defect sites along the side walls [36]. Fig. 1 shows the FTIR spectra of MWCNTs and acid-treated MWCNTs. The appearance of sharp peaks at 1642 cm-1 indicates the presence of carbonyl groups (C=O) of the quinine type units along the side walls of the nanotubes [37], and its intensity decreased after acidification. Two noticeable peaks appeared at 1737 and…

condensation. An aldol condensation is when an enolizable aldehyde or ketone undergoes a reaction, in the presence of a base or acid, and gives a beta unsaturated ketone or aldehyde (Utah Valley University, 2009). This type of reaction can also add carbonyls to a compound, using similar methods to the Grignard reaction. It is also important to note that in order for this reaction to occur, an alpha hydrogen must be present on one of the reagents (Farmer, 2013). In the following experiment,…

Abstract A spontaneous, one-pot strategy for the room temperature biosynthesis of gold nanoparticles (AuNPs) using Cocos Nucifera Linn (coconut palm) coir extract is described. The formation of AuNPs was observed within 30s of reaction time between the metal precursor and coir extract. The bioextract acted as both reducing agent and a stabilizer. The influence of various experimental parameters such as % volume fraction of coir extract, concentration of metal precursor, contact time and solution…

eating healthy. A polypeptide chain is a chain of amino-linked together by peptide bonds. The foundation of the polypeptide is given by the repeated sequence of three atoms of every deposit in the chain: the amide N, the alpha-Carbon , and the Carbonyl C. the rotations in the chain occur about the bonds in the back bond , where as the peptide bond ordinarily is unflexible . The presence of an amino gathering…

that the functional groups present in the starting material, 2-methylcyclohexanone, in no longer there in the final product. The main identifying peak to confirm this would be whether or not a peak is present around 1700 cm-1, which would indicate a carbonyl group. That peak is not present in the IR spectrum, meaning that the starting material is not present. As for percent yield it was 57%, meaning that of the total possible amount of product that could have been collected under ideal…

The struggle to find an effective method to quit smoking has affected people for a number of years. As the effects of cigarettes became more sever people used many different replacements for the nicotine additive in cigarettes. Nicotine is a stimulant, and also a highly addictive quality of tobacco. When smoking a cigarette you burn the tobacco to release the nicotine, but in this process you also release “tar”. Tar is the collection of carcinogens (cancer causing agents) that you inhale with a…

Schiff base Method preparation for Schiff base ligand is a straight forward synthesis and easily modified using different amines and carbonyl compound. This could be one of the reasons that make Schiff base ligand popular in coordination chemistry research. Synthesis of Schiff base ligand commonly, taking place in alcohol through condensation reaction of amines and carbonyl compound. The acid/base catalysis or heating is employed in the synthesis of Schiff base as their reactions are mostly…

Introduction: The purpose of this experiment is to determine the product that is produced from sodium hypochlorite oxidizing 2-ethyl-1,3-hexanediol and this experiment is to also determine if sodium hypochlorite is a selective oxidizing agent. This reaction is an oxidation reaction. The reaction involves the removal hydrogens and sometimes the addition of oxygen. 2-ethyl-1,3-hexanediol will undergo an oxidation reaction to produce an unknown product (Scheme 1). (1) Scheme 1.…
