Ferrous

This method was carried out with slight modifications (Hossaina et al. 2008; Li et al. 2012). The FRAP method measures the ability of the antioxidants to reduce ferric–tripyridyl-triazine (Fe3+-TPTZ) complex to the blue colored ferrous form which absorbs light at 593 nm. The ferric-TPTZ reagent was prepared by mixing 300 mM acetate buffer, pH 3.6, 10 mM TPTZ in 40 mM HCl and 20 mM FeCl3.6H2O in the ratio of 10:1:1 (v/v/v). The FRAP reagent was freshly prepared before each experiment…

Olds, who founded Olds Motor Vehicle Company in 1897 (later, as Oldsmobile, to become a part of General Motors). Having left his company years before it was acquired by GM, in 1905 Olds established a new company, REO Motor Car Company, the predecessor to Nucor, in Lansing, Michigan. Though Olds' cars, including the luxurious REO Flying Cloud, were popular, they were not profitable, and the company's more successful truck business (featuring the famous REO Speed Wagon) was still not sufficiently…

The form of iron found in foods which is (Fe3+) is different to the type of iron that is absorbed by the body Fe2+ 2. Fe3+ is an iron mixed with oxygen, this is an insoluble form of iron 3. However, the body converts this iron into the form of ferrous which is soluble (Fe2+) 3. Iron is a vital component of not only the human body but also other living things 3. This is due to the fact that it performs many metabolic processes, such as electron transport, oxygen transport and it is also crucial…

Coordination complex A coordination compound is the result of the reaction of lewis acid and lewis base in which neutral molecules called ligands make coordinate covalent bond with middle metal atom. Ligands have one electron pair to donate to a metal atom and are called complex agents. • Metal atoms are Lewis acids because they can accept pairs of electrons from Lewis bases. • Within a ligand, the atom that is directly bonded to the metal atom/ion is called the donor atom. • A coordinate…

Poison in Disguise Food—it is loved by all, required for life, but widely abused. The food industry has come under attack, especially in the last few decades, by nutritionists and doctors concerned by the overwhelming health problems in the developed world. Diabetes, heart disease, and obesity are just a few of the myriad issues impacting Americans today. Consumers must become educated on food labeling so that they can avoid foods dangerous to their health, and become more active in demanding…

Grigori Rasputin did not live very long but his life was indeed very interesting. Over and over again, his life is described as “sorted” with three major emphases: his sexual exploits, his unorthodox behavior and his untimely death. Very little effort has been made to describe and discuss the impact that he had on Russia’s’ efforts during World War I. Although World War I was significant to the development of post war occurrences and ultimately today’s society, Rasputin was a key player but…

I. The clinical presentation of the disease. According to the National Institute of Health, fatigue is the most common symptom of every type of anemia. The fatigue is caused by a decrease in red blood cells to carry oxygen throughout the body. Other anemia symptoms due to decreased oxygen carrying capacity are: shortness of breath, dizziness, headache, coldness in hands and feet, pale skin, and chest pain ("What Is Iron-Deficiency Anemia?," 2014). The erythrocytopenia causes the heart to exert…

Navistar International Corporation is currently America's largest manufacturer of medium and heavy-duty diesel trucks. Until 1986, Navistar was known as International International Harvester, a leading manufacturer of agricultural and construction machinery, with 47 manufacturing plants. Years of dramatic financial losses, however, forced the company to sell off these primary businesses to focus on the production of diesel trucks, a move that necessitated the layoff of thousands of workers and…

There were many tests performed on my unknown, which led me to conclude that the unknown microorganism is Pseudomonas fluorescens. When determining the gram reaction of the unknown, a Gram stain was done. This process differentiates between a Gram-positive and Gram-negative microorganism. This is done in four steps. The microorganism was stained with iodine, crystal violet, alcohol and acetone, and safranin. Iodine was used first as it acts as a mordant. It forms an insoluble complex by binding…

Prussian blue is used to treat thallium and radiocesium poisoning by combining the two in the intestines and stops them from being re-absorbed into the body. Overview Prussian blue treats patients with thallium or radiocesium poisoning by binding the two isotopes in the gastrointestinal tract and the combination removes the poison from the body through the patient’s stools. With the removal of thallium or radiocesium through the stool, the harm to the patient’s tissues and organs remain…
