Citric acid

Malachite Green Assay: The reaction that AGPase catalyzes produces PPi. The resulting PPi that is produced is hydrolyzed by an inorganic pyrophosphatase (Sigma Aldrich) to generate phosphate (Pi). Each reaction for the assay was conducted on a 96 well plate and the reaction mixture was 50µL and contained Pre-Mix which contained 50mM HEPPS, pH=8.0 (MP Biomedicals), 10mM MgCl2, 1.5mM FBP (Sigma Aldrich), and 0.2mg/mL Bovine Serum Albumin (Sigma Aldrich), and 1.5mU/µL yeast inorganic…

drinks and citric juices are the top contenders in dental erosion. The reason being there are acids contained in these drinks that dissolve any hard surfaces of the teeth that are exposed, such as the enamel. If the protective enamel is gone, the inner part of the teeth are left exposed. This leads to sensitivity. Also, not only can these acids dissolve outer surfaces, it can also damage the internal parts of one’s teeth; thus leading to the saliva’s ability to repair the teeth weakened.…

By using the bioinformatics information, we can determine that the non polar amino acids affect the bonding with hydrogen bonds. This means that the pH of the enzyme will be physiological. It can work better at a pH concentration of 7, and actually the cells can survive in that environment. Meaning, enzymes can work well with this concentration of pH, so it bonds do not break easily when it can be saturated of acid or base. 4. As our experiment says, the three different amylase will have…

On the experiment 1 solvent abilities: All solutes were expected to dissolve in water because water is known as “universal solvent.” Observation showed that many salts and sugars were able to fully dissolve in the water solvent, but corn oil did not (Figure1).The reason salts would dissolve into water solvent because water molecule carried partial positive charge on hydrogen atom and partial negative charge on oxygen atom; they could react with cation and anion from salts that have ionic bonds…

This paper describes the process by which a three-component mixture was separated and identified. The mixture was separated with the aid of a separatory funnel and various solvents acids and bases. The compound was found to be comprised of meta-nitroaniline, naphthalene, and benzoic acid / 2-napthol. All three of them are organic compounds with melting points in the order they were listed 111-114, 79-82 and 121-122/121-123 °C. the percent yield of each component was also calculated at the end…

3.2. Chemical quality parameters and pH value:- 3.2.1. Chemical quality properties, pH values and total plate count (TPC):- Total volatile basic -nitrogen (TVB-N), the peroxide value (PV), pH and total plate count (TPC) are good index to determine the freshness and quality of fishes and their products. Data presented in Table (4) show the values of TVB-N, PV,…

3.1: Ligand preparation: A series of benzimidazole derivatives were used to prepare the ligand dataset using benzimidazole as the query molecule. All the inhibitors selected comply with the Lipinski rule of five. A total of 50 molecules were taken up for the study. 3.2 Virtual screening: To further screen the compounds, additional similarity metrics were calculated by ROCS. ROCS is a shape based superposition method used to perceive similarity between molecules based on their three dimensional…

and [HI] will decrease. 4. 20 grams of magnesium were placed in a conical flask. Which one of the following solutions, if added, would produce 100 mL of hydrogen gas the fastest? A. 100 mL of 4 M sulfuric acid B. 200 mL of 2 M sulfuric acid C. 400 mL of 1 M sulfuric acid D. 50 mL of 8 M sulfuric acid 5. Why does the rate of reaction increase when powdered calcium carbonate is used instead of marble chips? A. The powdered calcium carbonate acts as a catalyst. B. There is an increase of the…

The substances found on the victims of the crash can be easily identified through simple math. You start by taking the percent values of each element found in the substance and changing it to grams, where one percent equals one gram, so that each element is out of one hundred grams. After finding the grams, you find out the moles of each element by multiplying the gram amounts by the conversion factor, which is 1 mol over the molar mass of the element you are dealing with, 12.01 grams for carbon…

THEORY An acid is a proton (H+) donor A base is a proton (H+) acceptor EXPLANATION OF THE THEORY: Acids are proton donors and bases are proton acceptors. A hydrogen ion is the same thing as a proton since hydrogen consists of a proton and an electron. When hydrogen loses an electron all that is left is a proton. According to the Brønsted-Lowry theory of acids and bases, when an acid and a base react, a conjugate base and a conjugate acid will be produced. EXP: acid + base à conjugate acid+…
