Vitamin losses can occur through chemical reactions which lead to inactive products. With regards to food chemistry, the main concern is to maximize vitamin retention by minimizing aqueous extraction (leaching) and chemical changes such as oxidation and reaction with other food constituents for a small vitamin deficiency can already cause diseases in humans (Fennema, 1996). Vitamins are mainly classified into two based on solubility: the fat soluble vitamins and the water soluble vitamins. Fat soluble vitamins are composed of Vitamins A, D, E and K while
Lactase is effective at pH 2 – 7 (including dH2O) and therefore breaks down the lactose sugar in milk into glucose and galactose. As a result, the test strips will turn a shade of brown. . Lactase is not effective at pH 10 – 12. At the high pHs, the enzyme lactase is denatured and is no longer able to break down the sugar lactose in milk.
Carb-Cutter; Blocker of Carbs or a Phony? Rumor has it that there is a miracle weight loss product that slows down the digestion of carbohydrates. These diet pills contain carb-cutter which blocks amylase, the enzyme that breaks down starch into glucose. With this being done, Carb-Cutter neutralizes the amylase before it starts the breakdown. This allows your body to pass starch through without turning it into glucose.
Vinegar, Antacid, and Soap all became positive solutions after I put in the enzyme. A change in pH disrupts an enzyme's shape and structure. pH measure acidity--water is neutral and has a pH of 7. When the pH changes an enzyme's structure, the enzyme can't do its job. Changes in pH break the delicate bonds that maintain an enzyme's shape.
B: Ingestion of an acidifying drug in this case is to blame. With the introduction of Topamax to Mary’s system, the Topamax begins to inhibit her renal carbonic anhydrase causing metabolic acidosis. 9. B: IV of HCO3- in isotonic solution is the best option and my recommendation. Even with the carbonic anhydrase being inhibited and causing metabolic acidosis, direct injection
Lab 5: Precipitate Patterns October 31st, 2013 Partners: Muhammad Saeed, Kristian Palmer and Kyle Poirier By: Rauman Tuan-Kichil For: Mr. Fontaine Investigation: Wastewater from metal manufacturing processes often contains toxic cations. These ions must be removed before the water can be released into the environment. Many of these ions can be removed using precipitation reactions. For example, recycled car batteries contain toxic lead cations, Pb 2+. These can be removed by adding a solution of potassium iodide, KI.
Purpose: Establish which salt solution would prove to be the most cost effective for the company to produce hot and cold packs that reach temperatures of 65° C and 0° C, respectively, as well as their relevant prices of production. Introduction: The Dystan Medical Supply Company is searching for a salt solution for their hot and cold packs that will be most cost effective. The cost of production per pack must be less than $5.00 for the company to make a profit. Four salts: ammonium nitrate, calcium chloride, lithium chloride, and potassium chloride will be tested to find to most cost effective solution. The salts will be dissolved in distilled water by small quantities until the reaction reaches When ionic compounds dissolve in water, they either absorb energy from or release energy to the surroundings.
Andre’ Dorsey Mrs. B Lab section: Alka-seltzer Experiment In this experiment we wanted to see what would dissolve the Alka-Seltzer the quickest using these three beverages: orange juice, milk, and water. Alka-Seltzer is a pain reliever for minor aches, pains, fever, headache, heartburn, indigestion, and hangovers. What I think about the experiment is that the orange juice would dissolve the Alka-Seltzer the fastest out of the three beverages because it is a acid. The materials used for this is experiment were: beaker a constant, Alka-Seltzer a dependent variable, stop watch a constant, 100ml of water a dependent variable and also a controlled group, orange juice independent variable, and milk independent variable. Procedures for
If Eugene’s blood PH is really low than administering sodium bicarbonate (NaHCO3) will help him get back to the range of 7.35 - 7.45. The NaHCO3 will act as a buffer by mixing with acids in his body and then reduce the acid-base imbalance. Since Eugene is a chronic alcoholic I would also run a kidney liver function test to check his enzyme levels, because a if they kidney or the liver is failing then it is not removing the toxins in the body and that will cause a buildup of toxins in the blood stream, resulting in brain
pylori can be performed easily and rapidly. However, blood antibodies can persist for years after complete eradication of H. pylori with antibiotics. Therefore, blood antibody tests may be good for diagnosing infection, but they are not good for determining if antibiotics have successfully eradicated the bacterium. The urea breath test (UBT) is a safe, easy, and accurate test for the presence of H. pylori in the stomach. The breath test relies on the ability of H. pylori to break down the naturally occurring chemical, urea, into carbon dioxide which is absorbed from the stomach and eliminated from the body in the breath.
