Eicosapentaenoic acid

the temperature at a range between 25-55 °C (Pasupuleti & Braun, 2010). During alkaline hydrolysis of proteins, some amino acids like serine and threonine are damaged during alkaline hydrolysis, however, tryptophan remains intact. Also, this process causes racemization of amino acids, by modifying its structure and converting L-amino acid in its isomeric forms D-amino acids (Wisuthiphaet & Kongruang, 2015). Disulphide bonds are also fragmented with loss of cysteine, serine, and threonine and…

One of the parameters that determines water quality is pH. It is defined as the negative logarithm of the hydrogen ion and is intended to be a measurement of the balance of acids and bases. Temperature affects pH. In pure water, a decrease in pH of 0.45 occurs when temperature is increased by 25°C [11]. There are several methods for measuring pH. The most common is the use of a glass electrode sensible to it, a reference electrode and a measurement device. Another method is the use of…

The purpose of this experiment was to learn techniques to determine the freezing point of a pure benzophenone, a solvent. Furthermore, methods for determining the freezing point depression in relation to the solute, cyclohexanone, concentration were employed in addition to learning what molality is and how it related to the colligative properties being studied. These objectives were achieved by melting both pure benzophenone and benzophenone/cyclohexanone solutions (two solutions with…

Freshwater Treatment for Amoebic Gill Disease Freshwater treatment for AGD requires checking for few things before and during the treatment to carry out a successful and effective treatment. 1. Freshwater Source: The freshwater source should be checked for temperature, total ammonia nitrogen and ammonia percentage, pH, hardness, salinity and any harmful plankton. Temperature: Freshwater with temperature closer to the temperature that treating fish are being reared in is best choice. Colder…

In this study, multiwalled carbon nanotubes@poly(p-phenylenediamine)-prussian blue (MWCNTs@PpPD-PB) nanocomposites were synthesized and used for the nonenzymatic electrochemical detection of hydrogen peroxide (H2O2). The PpPD layer also helps the MWCNTs to be dispersed in the water together with the PB formation and fixing on the surface of the MWCNTs. Moreover, PpPD, a conductive polymer, increases the electronic conductivity and stability of MWCNTs. By combining the selectivity and catalytic…

Gravimetric Analysis of a Metal Carbonate Purpose The purpose of this lab is to find the mass of an unknown metal by conducting a double-displacement precipitation reaction, which is our gravimetric analysis. Once we find the precipitate mass, we can then find the molar mass by using the molar ratio given in the reaction equation. Procedure First, we set up the ring stand with a Bunsen burner, put a crucible on top of the pipe stem triangle and heated the crucible for a minute, then let it…

2.8.4 Properties The application of carrageenan as food additive depends on its performance such as forming thick solution or gels. For example, κ− carrageenan forms strong and rigid gels with potassium salts, forms brittle gels with calcium salts, clears gel with sugar addition, and exhibits syneresis. On the other hand, ι− carrageenan forms elastic gels with calcium salts, clears gel with no syneresis, and creates a gel that is freeze/thaw stable, while λ− carrageenan is not gel-forming but…

cells There are 3 main types of commercially available cells: 3.1.1Mono crystalline Silicon PV& Polycrystalline Silicon PV The occupational health issues are associated to chemical burns and inhalation of fumes from hydro fluoric acid (HF) and other solutions of acids (e.g., HNO3) and alkalis (e.g., NaOH) used for cleaning wafers ,removing complete oxide layer, and cleaning the reactor. Performing the slicing of wafers also results in solid waste for example (e.g., small pieces of…

Betacyanin pigments from beta vulgaris vacuoles were use in this experiment to determine the various effects of diffusion into its surrounding environment: 60%detergent, which is shown in the figures below. The four figures below are a set of data that were collected and analyzed the effects of time, salt concentration and ionic compositions on the rate of diffusion. Both figure one and two show a set of measurements between two different salt concentrations representing their absorbance versus…

In experiment 2, we observed that the reaction of halogenoalkanes with aqueous alkali and water which contains dissolved silver nitrate. Halogenoalkanes are alkanes which have one or more hydrogen atoms replaced by halogen atoms such as fluorine (F), chlorine (Cl), bromine (Br) and iodine (I) which are the elements in group 7 in periodic table. Halogenoalkanes have the general formula, RX, whereby R is an alkyl or substituted alkyl group and X is any of the halogen atom. Besides, halogenoalkanes…
