Phosphorus is an important part of the human bones, it is good for the brain, kidney, heart, and blood. Majority of your body contains 85% of phosphorus in your body. Phosphorus is found in protein- rich food like meats, poultry, fish, nuts, beans and dairy products. Phosphorus is a Greek word for light bearing. On the periodic table phosphorus is a chemical element with the symbol (P) and is also a nonmetal. Phosphorus was discovered in 1669 by Hennig Brand, who was a German physician and alchemist. Hennig Brand thought that he could turn phosphorus in urine into gold, but everytime he tried he ended up getting a white, waxy substance that glowed in the dark. When Hennig Brand didn’t succeed phosphorus became an element used in deadly explosives.
Sulfur goes back to the ancient times but it was called brimstone. In 1979, a French chemist named Antoine Lavoisier recognized sulfur was an element and added it to his list of elements. The element sulfur is considered a nonmetal and is the 10th most abundant element in the universe. On the periodic table sulfur is in group sixteen and it is a representative element. Sulfur has an atomic mass of 32.07 with an atomic number of 16. There are three energy levels for sulfur the first energy level is two, the second energy level is eight, and the third energy level is six.
Although some of the elements have been known for thousands of years, our understanding of many elements is still young. Mendeleev’s first Periodic Table contained only 63 elements, and about that many were discovered in the following 100 years. Just like countries, emperors, philosophers, and cities, elements have histories, too.“The Disappearing spoon” by Sam Kean, is a detailed history of the elements on the Periodic Table. Kean does a important job of telling every single element’s journey throughout the history of mankind: from the earliest times, when chemistry was intermingled with alchemy, to these days of modern chemistry. For example: Thallium is considered the deadliest element, pretending to be potassium to gain entry into our cells where it then breaks amino acid bonds within proteins. The CIA once developed a plan to poison Fidel Castro by dosing his socks with thallium-tainted
Arsenic is element 33 on the periodic table and is in Group 15. Arsenic is obviously an extremely poisonous element; however, some people have found arsenic to have a restorative effect on them. Chemically, arsenic is a metalloid. Two common forms of arsenic are gray and yellow. (see Figure 1-A) Element 33 has an atomic weight of 74.9216 and the chemical symbol of As. It boils at 613ºC, melts at 817ºC, and has a density of 5.72. (see Figure 2-A) The element has been known for centuries and can be easily obtained from ores such as arsenopyrite (FeAsS), realgar (As2S2), orpiment (As2S3), and arsenic trioxide (As2O3). There are many uses for arsenic. Among them is in the manufacturing of glass to eliminate the air bubbles and the green color caused by contaminated iron compounds. Arsenic is also added to materials such as lead and copper alloys to increase the strength and better the corrosion resistance. Although it is well known that arsenic is often used in tales (both true and otherwise) as a killing agent, arsenic has been used as a curative as well. Before penicillin was introduced, arsenic played a significant role in the treatment of syphilis. Other good uses for element 33 are as insecticides and semiconductors. Gallium arsenide (GaAs) is a known semiconductor that is also used as a laser material. A good test for the detection of arsenic is the Marsh test, invented by James Marsh, an English chemist.
Arsenic has been one of the elements most mentioned during the middle and even modern age. It was formerly known by Chinese, Romans, Greeks and even earlier, by the Babylonians. The Greeks used the arsenic oxide (III) as a depilatory, and 4,000 years before the Christian era, arsenic was involved in the development of early bronzes. However, the arsenic was released in early civilizations through compounds or substances containing the element, which by its color and appearance would favor the conversion of base metals into gold. It was also used by the alchemists in the method of making the pill of immortality. In the philosophy of alchemy, arsenic represents the masculine principle. The masculinity of arsenic was different, because it combined with an element that was considered as masculine such as sulfur, forming orpiment and realgar.
A huge fascination of arsenic started in the 19th century when people got word of a province in southeastern Austria where people ate arsenic. Women would eat arsenic to help gain weight and fix their complexion to look more beautiful and men would eat arsenic because they believed it helped them breath easier when they were climbing high up in the mountains. One doctor by the name of Dr. Robert Craig MacLagan, was particularly interested in this and visited the town to see for himself what was really occurring. He observed the people and tested their urine to prove that they have been indeed ingesting arsenic. He wrote about the things he witnessed in the Edinburgh Medical Journal. The men in the town would eat 6 grains/dose at least twice a week, sometimes eating it on their bread or just drinking it with their water. As a result many Victorians began self-medicating themselves with arsenic.
Education plays a dominant role in the lives of students all over the United States. Since most students spend roughly eight to twelve hours in school, it is important to make sure that they are provided with a healthy and nutritious breakfast, lunch and snack.
The late Nineteenth Century saw increased industrial growth in the United States. One of the major developments that led to the increased industrial growth was the expansion of the railroad. The railroad provided infrastructure that made it cheap to transport goods from one place to another. Investors could now build industries in different parts of the country and transport products fast and to a wide network of consumers. Another resource that fostered industrial growth was the influx of immigrants into the United States. During this time, many foreigners were able to come into the country and provide cheap labor for building industries thus reducing the cost of industrialization. In addition, the country was in need of vigorous development to cater for the needs of the growing population at that time.
When one hears the three words: vitamins, nutrients, and minerals, they think of one thing-being healthy and noticing what your intake is daily. Nutrition is all about vitamins and nutrients. Firstly, vitamins are an organic compound required by the body in small amounts of metabolism, to protect health, and for proper growth of children. Vitamins also assist in the formation of hormones, blood cells, nervous systems chemicals, and genetic material. There are 13 well-identified vitamins. Some examples of the 13 well-identified vitamins are: A, D, E, and K-fat contained foods, B, C-consumed immediately. A well known and commonly used in commercials for orange juice vitamin is vitamin C. Vitamin C or ascorbic acid is important in the synthesis and maintenance of connective tissues. The lack of vitamin C will result in a sickness called scurvy. Scurvy harms the gums, mucous membranes, and the skin. Another well-known vitamin and is also used to commercial to give more information about this beverage is the vitamin in milk. The vitamin in milk is vitamin D. If you do not drink milk and obtain this vitamin, your bones and teeth will become soft and weak. Lacking one or more of the 13 well-identified vitamins will cause sickness and weakness to your body. Secondly, nutrients are how the body assimilates certain compounds. Nutrients are classified in 5 major groups: proteins, carbohydrates, fats, vitamins, and minerals. One of the five nutrients is carbohydrate. The carbohydrate group principally consists of sugar, starch, dextrin, cellulose, and glycogen. In more basic terms, carbohydrates are sugars needed by human and other living organisms. Some types of foods that contain carbohydrates would be candies, ice cream, fruit juice, soda, chocolate bars etc. Lastly, vitamins are connected to minerals. Minerals are also a very important part of a healthy person. There are 11 major groups of minerals. They are: calcium, chromium, copper, iodine, iron, magnesium, manganese, phosphorous, potassium, selenium, and zinc. All these terms look very familiar if one has taken chemistry. These are the elements of our world. One of the more common minerals that most people have heard of is calcium. Calcium also helps with the structure and strength of teeth and bones. Vitamins and minerals work together to help humans maintain a healthy body. For example, vitamin D works with calcium to help for and maintain the strength of teeth and bones.
Flame retardants that contain phosphorus produce phosphoric acid when exposed to the heat of the flame. Phosphoric acid reacts with the burning material to create a thick glassy layer of carbon that protects the rest of the material from thermal degradation, slows the fire down and eventually stops it.
Kidney Function Introduction and definition of terms: The kidneys are the main organs in the urinary system. They filter waste products out of blood from the renal artery. These are then excreted. Useful solutes are reabsorbed into the blood. They also have a major homeostatic role in the body, and help to control the water content (osmoregulation) and pH of the blood.
Platinum, symbol Pt, is a relatively rare, metallic element that is more expensive than gold. The atomic number of platinum is 78. Platinum is one of the transition elements in group 10 of the periodic table. Platinum is the most important of the group of elements called platinum metals. Also included in this group are the metals ruthenium, rhodium, palladium, osmium, and iridium. Platinum metals were probably used in alloyed forms in ancient Greece and Rome and were first mentioned in European literature in the early 16th century. The separation of the other platinum metals from platinum and from each other was accomplished in the early 19th century.
Proteins (macronutrient), which are found in animal products, nuts and beans, they help to build new cells, maintain tissue and synthesis new proteins essential for performing basic bodily functions. Proteins are in abundance in the human body and are present in the outer and inner membranes of all living cells (Dummies, 2018). Proteins are essential for building new cells, maintaining tissue and helping new proteins needed for basic bodily function (
“If we could give every individual the right amount of nourishment and exercise not too little not too much, we would have food the safest way of health” (Barasi.E.M, 2003). This essay is going to discuss on the important of six essential nutrients in human body. According to PosnerB.M (1998), he define essential nutrients as a nutrients that the body cannot synthesize on its own-or not to an adequate amount and must be provided by the died. Oxford dictionary (2009), also define essential nutrients as are those nutrients that are required by the body and cannot be synthesise in the adequate amount to meet requirement, so must be provided by the diet. Essential nutrients are those found to be essential to human life and optimal function, Williams.M. H (2006).There are six main type of nutrients used to maintain body health. They are carbohydrates, protein, fat, vitamins, minerals and water. They must be in balance for the body to function properly.
Water is an essential nutrient that our body requires every day. Without water human life cannot be sustained. Water deprivation kills faster than lack of any other nutrient. People do not think of water as a nutrient and don’t realize the important role of water in the body functions.
People do not know what is a vitamin, what they do and why human body required them. However, they exist numerous types and kinds of vitamins, for example, Vitamin A, B, C, D, E and K; human body requires some more than others. Dr. Karl Forkers says that, “A vitamin is an organic nutritional substance present in low concentration in the body.” (1976, Dr. Forkers K.) This paper examines the importance of vitamins but also the disadvantages of the excess of consume on it, also analyzing vitamins in daily life like in low-fat products. The ignorance of the human and the bad nutrition closes the eyes of society because people don’t know what to do or eat to have a healthy body, so
