Introduction The research question is: the spectrophotometer determination of iron in teff and a measure of the bio-availability to suggest ways in which bio-availability or absorption is increased and consequently anemia decreased.
Iron is one of the most important elements that is needed by different living organisms. One of its functions is to control cell growth and aid in differentiation of cells. However, one of its most important responsibilities is found in hemoglobin. which is involved in allowing oxygen transport in portions of the blood. Iron is available in two oxidation states: Fe2+ and Fe3+. The one that is readily absorbed in the human body is Fe2+. Thus in this extended essay, I will focus on the concentration of Fe2+ in four cereals- teff, wheat, maize and sorghum. Limited amounts of absorption of Fe2+ in the human body causes iron deficiency anemia. Iron deficiency anemia is when a person has a red blood cell count that is less than normal or when there are few hemoglobin molecules in each red blood cell. Consequences and effect of this to humans could be fatigue,headaches, palpitations, lethargy and etc. One of the causes of iron deficiency anemia is the bio availability of many grains and legumes. The less bio available or in other words the less absorbed the nutrients of the cereals we eat are, the prospect of iron deficiency anemia occurring becomes higher. I will show this need of Iron in the blood by first measuring the iron contents of the four
2.Iron extremely impactful in our life. One, it carries oxygen from our lungs through the blood stream and releases it in the body where it’s needed. Is also built into the enzymes that help us detoxify poisons and convert sugars and energy. Iron is also responsible for the healthy immune system function. Without enough iron in our system, skin gets pale, people can feel confused, dizzy, cold, and extremely fatigued. It explains why some areas of the world’s oceans are
The most prominent cause of Iron Deficiency Anemia is bleeding. Blood loss from the Gastrointestinal Tract is a significant cause of anemia for both men and women. When blood is present in excrement, a gastrointestinal problem exists. Many times, people are unaware of these problems with their waste products. When they begin to feel the symptoms of anemia and undergo tests that determine that they are anemic, it begins the process of discovering more health problems. Anemia can serve as the precursor of certain diseases. There are many instances when it is merely a sign of severe disease such as a peptic ulcer disease, gastritis, hemorrhoids, angiodysplasis of the colon, and colonic adenocarcinoma (http://www.physsportsmed.com/issues/sep_96/browne.htm).
Too much iron is toxic to your body. If the excess iron is left untreated it can damage joints, organs, your liver could become enlarged, liver failure, liver cancer, or cirrhosis which is scarring of the liver. This can result in the organs to not working well. If your heart gets too much iron it can produce an irregular
Iron deficiency anemia, one of the most common types of anemia, is a blood disorder where
Iron is used in metabolical functions, in red-blood cells to carry oxygen, and in enzymes, to speed up reaction rates. One molecule that contains iron is hemoglobin, found in red-blood cells.
Iron is one of the important minerals that is required for our bodies to function properly. Most of the iron in our body is found in the blood such as haemoglobin, approximately 60 -70% of the human body’s iron is found in the haemoglobin, a protein in the blood that transports oxygen. Iron is also present in muscle tissue and some enzymes. There are two types of iron in the body which are “Heme Iron” from animal products and “Non-Heme Iron” vegetables and
Research which ion this is and state if it is a cation or an anion. Discuss the significance of this ion in relation to oxygen transport. Iron (Fe) is a cation. Iron complexes are utilized in the transportation of oxygen in the blood and tissues. When the iron is bound to oxygen, the haem group is bright red (oxyhaemoglobin) however when it lacks oxygen (deoxygenated) it is blue-red in colour.
Iron is an important nutrient because it helps carry oxygen in the hemoglobin in red blood cells around the human body. When a healthy iron supply is reached, the body immediately stops absorbing the nutrient, and just lets it past through the digestive system. However, people with hemochromatosis absorb all the iron from the food consumed, past healthy levels. All the extra iron spreads throughout the body, and unevitably causes great damage to major organs and almost all other parts of the body. According to Survival of the Sickest, "hemochromatosis can lead to liver failure, heart failure, diabetes, arthritis, infertility, psychiatric disorders,... cancer," and other diseases if left untreated (Maulem
In previous studies, it has also been seen that overweight or obese individuals are at greater risk of iron deficiency than normal weight individuals. Some studies suggest that possible explanations for this poor dietary iron intake, is increased iron requirements and/or impaired iron absorption. Nutrient Metabolism and Cardiovascular Diseases (2015), concluded that a calorie reduced diet causes the BMI to decrease however, their data showed that ferritin increases with BMI. The American journal of pathology (2013), demonstrated a model of iron overload syndrome in which an iron enriched diet induces insulin resistance, hyperglycemia and visceral adipose tissue. These contradictions causes us to question if iron plays a role in obesity and obesity related insulin resistance. Turk J Haematol (2014), scientists wanted to assess whether dietary iron overload influenced glucose and lipid metabolism as well as insulin resistance in mice, and found that a more iron enriched diet increases serum and hepatic iron while lowering IRP binding activity.
In the beginning of every cross country season, my coach stressed the importance that all the female runners must take one iron pill a day. I never gave in to this because he never gave us an explanation, so I saw this as merely a mental booster rather than actual improvement present in my body. After doing some research, I found out that iron is an essential nutrient used by the human body for to transport oxygen and produce energy. Iron is present in every single cell of the body and carries oxygen from the lungs to the tissue in the form of hemoglobin, which is the oxygen-transport protein in red blood cells. Lack of iron results in both fatigue and weakness, which is definitely harmful to a cross country runner. Iron deficiency affects women about 8-10 times more than men, which is why it is crucial for women runners to watch their iron levels (Sinclair, Hinton). If iron deficiency worsens, it can lead to anemia. Anemia is when you do not have enough red blood cells, and as a result, less hemoglobin. If a cross country runner has anemia, it can affect their whole season because they are exerting energy without the sufficient amount of oxygen needed to complete each run or workout.
The purpose of this essay is to determine the type of anemia that Ms. A most likely has based on her preliminary workup. Ms. A’s anemia will be discussed including potential side effects and cases. Finally, recommendations for improving Ms. A’s anemia will be discussed.
Conferring to the case study 1 of Ms. A, who is suffering from iron deficiency anemia. “People who experience iron deficiency anemia lack adequate iron required to produce hemoglobin. Hemoglobin supports red blood cells in carrying oxygen all through the body” (Mayo Clinic, 2014). In this presentation, the writer will provide rationales where Ms. A is presenting signs and symptoms of Iron Deficiency Anemia.
According to the American Society of Hematology, approximately 35 million people in the United States are over the age of 65, and almost 10 percent of this population is currently anemic. Anemia occurs when red blood cell counts drop, or when red blood cells do not contain enough hemoglobin. In chapter seven of Biology Today and Tomorrow without Psychology, we learned hemoglobin is an oxygen-binding protein in red blood cells that consists of four polypeptides (2-alpha globins & 2-beta globins). Each globin holds a cofactor called a heme, and each heme has an iron
(2)The author points out many ways in which iron impacts life. Identify/describe at least five. 1. Hemoglobin to carry oxygen 2. oceans "seeded" with iron can hold more oxygen producing organisms. 3. Parasites feed on human iron. 4. Cancer cells thrive on human iron 5. High levels of iron can counter-act the effects of antibiotics, by feeding the bacteria to the point that they can live despite the antibiotics
Iron has isotopes that manly in nutritional studies. Fe-57 and Fe-58 are being the to most use of iron isotopes. In fact, iron atomic number is 26, it has four natural isotopes. Iron’s isotopes that are Fe-54, Fe-57, Fe-58 also, Fe-55 that turn into an electron
