The other systems of metabolic pathway II is 4-hydroxy - isopropenyl benzene acted as precursors for the forming of p-hydroxybenzoic acid. Pathway III is the original carbon -carbon cleavage on bisphenol accompanied by oxidation causes the forming of hydroquinone (Fig 4). The similar kind of degradation pathway by bacterial isolates were reported (Zhang et al., 2007 and Janett Fischer…

individual amino acids. Each of them may have positively charge or negative charge depending on the pH of the milk. At certain pH value, positively charges and negatively charges of the casein will equal, so that the number of electrons equals to the number of protons. [1] Approximately pH 4.6 is the pH value that acid casein is precipitated and least soluble. In milk, which has a pH of about 6.6, the casein has a net negative charge and is quite stable. However, if there is addition acid adds…

Vinyl chloride’s toxic effects are released via gas or liquid form. First, the route of exposure and how the human body is affected is explained. I have then explained the correlation between mechanisms of action and mode of action, and receiving professional care to eliminate the effects of vinyl chloride. The effects of vinyl chloride on the human body, and how Bradford Hill’s criteria for causation is explained last. [Heading 1] The route of exposure, based on Thomas Fuller (2015), will…

Purpose: Determine the percentage of 2-ethanoylhydroxybenzoic acid in aspirin tablets. Introduction (including background information) : Before creating Aspirin, “sail alba” was used. In 1860’s, chemists discovered that Salicylic acid (2-hydroxybenzoic acid, C7H6O3 ) is the active acid in sail alba. Salicylic acid is relatively strong though. It can irritate and damage the stomach membranes and mouth. In 1889, ethanoate ester of salicylic acid was introduced by the Bayer Company. They named it…

this lab was to separate unknown compound 204, composed of an amine, a carboxylic acid, and a neutral component, into each of its three respective states. The unknown compound was separated using microscale separation of acidic, basic, and neutral components by liquid/liquid extraction. Liquid/liquid extraction is a very common method often used in work-ups and allows for isolation of neutral components using acid/base chemistry; this method is extremely helpful in separating reactants and…

Aim 1: Determine the amino acid sensing specificity of folliculin. Since folliculin’s has novel molecular function in amino acid sensing I plan to further understand whether FLCN specifically senses a certain amino acid and if this level of detection is enough to elicit an mTORC1 response. 1.1. Determine if folliculin’s novel molecular function in amino acid sensing is triggered by glutamine. mTORC1 activation by amino acids requires FLCN, whereby its lysosomal residence during starvation…

state. It was indicated that PANI nanoparticles structure has an average diameter of 50nm, while PANI nanorods structure was found to have an average length of 4µm and average diameters of 95nm. The effect of the PANI morphological structure on the Acid blue 25 dye decolorization process was studied. The PANI nanorods recorded higher rate of dye decolorization of 99% within 8min compared with PANI nanoparticles that recorded the same percentage decolorization within 16min. Keywords:…

2.2. Extraction process analysis The solvent is fed from the bottom and broth from the top since the mass separation agent or solvent has a lower density than the aqueous mixture. The raffinate phase contains most of water and traces of HAc, and solvent, whereas the extract phase includes most of the solvent, HAc, and traces of water. The amount and composition of the mixed solvent significantly important for the process economy because it directly affects the composition of HAc in the extract…

determine pH levels of various substances using different methods. Two techniques were used, the pH paper indicator and the pH meter. Out of ten substances that were used, five of them were found to be acidic, namely: hydrochloric acid, coke, toothpaste, milk, and acetic acid. Sodium hydroxide, buffer solution, bleach, and the detergent were found to be basic. Bottle water was found to be neutral. Substances are said to be acidic because of having pH levels lesser than 7, and those having pH…

Purpose The purpose of the experiment was to see the effects of combining certain solutes and solvents. By conducting this experiment it is seen how solutions and mixtures relate to the six postulates of particle theory. When conducting this experiment, the particle theory was thought of, such as when you mechanically agitate a solution, particles move around and bump into each other, breaking up. The specific substances will be stated in the hypotheses. There were many things looked for when…
