It is very important that every human consumes food that contains the four main biological macromolecules: carbohydrates, proteins, lipids and nucleic acid. Macromolecules are vital because they help the body function on a daily basis from stimulating hormones, enough energy in the body to have movement and communication in the muscles, or structure for DNA and RNA. In each of the macromolecules, comprises of both Monomers (except lipids) that are small unit structures that form or associate with each other to build a Polymer chain. The Polymer can either assemble by dehydration synthesis (removal of a water molecule) or be dissembled through the process of hydrolysis (addition of water molecule). All humans should balance out variety of foods …show more content…
Oils rich in polyunsaturated fats also contribute vitamin E to the diet, an antioxidant vitamin most Americans need more of.” (SEP Staff (Chemistry of life lesson), Page 1) Although Complex Carbohydrates and Lipids are vital towards strong energy for the body, Proteins in foods such as eggs and meat play a vital role in the living organisms in the body because they are the building blocks for the functional processes. The complex protein molecule contains 20 different type monomers of amino acids that from the polymer (triglyceride). “Structural proteins such as collagen or elastin provide support. Regulatory proteins such as enzymes control cell processes. Proteins also play an important part in the immune system (antibodies), oxygen transport (hemoglobin), movement (muscles) etc. (American Heart Association, Page 1). The reagent that determines if there are any proteins in the substance is Biuret’s Reagent Solution. The objective of this experiment is to determine which macromolecule (or more than one macromolecule) is present in the food or liquid substance and to have an opportunity to understand the variety of food or liquid substances humans should consume or drink on a daily basis to help their body function …show more content…
• Exact amount of solution of the reagents (Benedict’s Solution, Sudan III Stain, Iodine and Biuret Reagent) for the specific tests (Simple Carbohydrates, Lipid, Complex Carbohydrates and Protein) was transferred into each of the test tubes.
• The size of the test tubes was constant.
• The room temperature was constant.
• The number of trials for each test was constant.
4. Control:
• The control group in this experiment was the distilled water.
1. Question: What do I want to find out?
• Which of the three food (or liquid) substances: milk, yogurt or oatmeal would help the Food and Drug Administration Center figure out the best food fight solution to stop the zombie growth population from invading the world?
2. Hypothesis:
• If the indicators for each macromolecule test determines which one of the three substances: milk, yogurt and oatmeal contains the most amount of proteins and complex carbohydrates and no simple carbohydrates that will stop the invasion of the zombies, then oatmeal will be the solution to the invasion because milk and yogurt contain a major simple carbohydrate: glucose and oatmeal is high in protein and complex
The unknown substance is probably a carbohydrate because it tested positive for starch which is a polysaccharide. This reaction also had very similar results as the Lugol’s test for potatoes which is a polysaccharide. Although the colors from the test for potatoes were not the same colors as the test for the unknown; the Biuret test had a slight color change and the Lugol’s test had a dramatic color change for both the unknown and potatoes. I am sure that the unknown was a starch, but the Benedict’s test for sugar was positive for the potatoes while the Benedict’s test for the unknown didn’t have a color change. The unknown probably did not have a color change for the Benedict’s test simply because there were not enough sugar present in the unknown for it to test positive. The Sudan IV Test for Lipids did not test positive for the unknown nor the potatoes because there isn’t a trace of lipids in starch. Based on my results, the unknown has a little protein, a lot of starch and no traces of lipids or
The independent variable for this experiment is the enzyme concentration, and the range chosen is from 1% to 5% with the measurements of 1, 2, 4, and 5%. The dependant variable to be measured is the absorbance of the absorbance of the solution within a colorimeter, Equipments: Iodine solution: used to test for present of starch - Amylase solution - 1% starch solution - 1 pipette - 3 syringes - 8 test tubes – Stop clock - Water bath at 37oc - Distilled water- colorimeter Method: = == ==
The Structure and Function of Carbohydrates Large biological molecules are called macromolecules, there are giant molecules (polymers) made up of repeating units (monomers). Carbohydrates are one of the main classes of biological molecules. Macromolecule units (monomers) are joined together by condensation reactions and hydrolysis reactions split macromolecules down into their individual units. Carbohydrates are molecules that contain elements of carbon, hydrogen, and oxygen. Carbohydrates have a 2:1 hydrogen to oxygen ratio, there are twice as many hydrogen atoms as oxygen atoms (the same proportion as in water).
Brains. Must have brains. There are a lot of far-fetched scenes that horror movies have filled in our heads over the years. Many elements of fiction have created varying degrees of panic, more so since the emergence of the false “Based on a True Story” label. There is one terrifying creature once thought to be fictitious that has recently gained popularity in the media as well as news channels around the world. A situation that would have negative global effects far worse than any other natural disaster previously experienced. But just what is this violent biological phenomenon that has people taking a second look at our understanding of pathogens and the effects of chemicals on biological organisms, you may ask. The simple answer is the very real possibility of a zombie outbreak. Zombies are a misunderstood being. The definition that used to be applied is that of a once living being revived from a posthumous state with a nasty appetite for flesh. However, the new definition of zombie is that which is being evaluated as an eminent fear. Zombies are widely accepted, currently, as a being that has been subjected to a biological change that incites rage, neurological defects and an enormous appetite for meat. Many factors contribute to zombies being considered a realistic threat to life as we know it; including but not limited to chemical products consumed by humans as well as viral infections with effects not previously researched in depth. Biotechnology is our best defense against our closest neighbors.
Our chicken sandwich has, by now, been broken down into digestible nutrients. The pancreatic juices have broken down the carbohydrates in the bread into monosaccharides (such as glucose and galactose) which leave the enterocyte by facilitated diffusion and enter the rich network of capillaries. They are transported in the blood stream and cross into the cytoplasm by Na+ cotransporters. Amino acids are moved to the circulation by facilitated diffusion. Lipids from the butter are broken down into fatty acids by lipases and are then absorbed across the cell membrane into the cytosol where they are reassembled into lipoprotein particles called chylomicrons. These are carried through lymphatic channels and into the circulation via the thoracic duct. The bloodstream carries simple sugars, glycerol, amino acids, and a number of salts and vitamins to the liver. The lymphatic system, a network of vessels that carry white blood cells and lymph fluid throughout the body, absorbs fatty acids and
...r can not be satisfied. The zombie is a consumer. Zombies are most often used as a metaphor these days for uncontrollable consumerism that plagues our generation. We blindly buy without thinking, either because of a low price, lust, or simply we just want more. We are guilty of “Zombie Consumerism”. Zombie consumerism is evident in George Romeros' film, Dawn of the Dead. In this movie, a shopping mall is where the characters take refuge and becomes the setting in which the humans stay in the battle of the zombies. They gorge themselves in free food and are delighted about having almost everything at their fingertips all to themselves. It sound's perfect. They can consume anything they want and they will be okay, forever. It is ironic then when there is nothing left and they must find new sources of shelter and food and resources, or become the resources themselves.
Zombies’ most obvious function is to the social taboo of cannibalism. Zombies violate the basic rule of what it means to be human: not eating people. This taboo is depicted best in George Romero’s Night of the Living Dead (1968). The scene, an hour and 15 minutes into the movie, shows several quick cuts and close ups of zombies ripping apart and eating “human” organs and limbs. The scene, a...
In recent years, there has been a huge increase of zombie related media in American pop-culture. Humanity has faced numerous crises and overcome them every time. The question has arisen that if a zombie epidemic were to occur would the United States have the ability to deal with it? The answer is yes. The United States has the ability to accept, adapt, and overcome an outbreak of such proportion. The U.S. has the manpower to rival the zombies’ growing numbers. The military and medical research staff have the technology to fight the spread of infection, and science and mathematics provide additional support along with pre-designed plans to do deal with such an outbreak.
Food contains variety of nutrients, which is essential to our bodies. Nutrition is necessary to support the activities of day-to-day living. Nutrients in the food help maintaining normal growth and development, tissue maintenance and repair, cellular metabolism, and organ function (Potter, 2012, p.996). There are two groups of nutrients: macronutrients such as proteins, carbohydrates, fats, and micronutrients such as vitamins and minerals. However, nutrition should include water too because water helps protecting and repairing cells from environmental damage. Each nutrient has its own functions to restore our body. Proteins rebuild damaged tissue and promote growth. Carbohydrates and fats provide energy to the body, while vitamins and minerals function throughout the body in support of body’s processes. Water is essential for cellular homeostasis and life: it removes waste products including toxins out of vital organs. It moves nutrients to the cells, regulates body temperature, and providing a moist for brain, eyes, ears, nose, mouth, spinal cord, and
The Benedict's Test is used to test the presence of simple sugars in a sample. If sugars are present, a color change will occur from blue to red. However, although the Benedict's test shows the presence of sugars, it cannot accurately determine the concentration of sugar in a sample solution. In our method, we added specific concentrations of glucose to the Benedict's test to use as a chart to estimate the glucose concentration of an unknown solution X. Although this gives a rough estimate of the concentration, it is very inaccurate. For example, the mystery solution X was a pale orange color, which was between the colors in my first and second test tube.
When the solution remains the same, it means the solution is negative control and does not have sugar. The presence of starch can be detected by using the Lugol’s iodine solution. If the unknown A, B, C milk samples turn to a dark blue color during the Lugol’s test, then these samples are positive control and also contain starch in them. But if the solutions turn to yellowish brown, it means these solutions are negative control
One of the four molecules is carbohydrates. Carbohydrates are made out of CHO. The main building blocks are sugars (saccharides). What carbohydrates do for us is they store fuel for our cells. They are fast paced and energetic.
= Before conducting the experiment I would conduct a simple test for the protein by placing a sample of the albumen into a test tube and add biurett reagent. This contains copper (II) sulphate and sodium hydroxide.
Cellular nutrition is the digestive functions within the human body. Without digestion the body is unable to make use of the foods an individual consumes until it has been broken down into smaller particles which can be dissolved in liquid (soluble particles). In the body there are two intestines known as the small and large intestine; in these intestines there are villi which are often described as finger-like structures (Herbalife STS, 2016). They work in the intestines to absorb all the nutrients from the foods an individual consumes. With poor nutrition the villi will slowly begin to close, thus there is a decrease in the rate in which the villi work at (Herbalife Nutrition Institute, 2016). The large intestine measures approximately sixty inches in length and works
The macronutrients a person consumes are what the body needs to function properly. They are the nutrients from protein, fats and carbohydrates that make up a person's daily nutrition. The amount of macronutrients and ratio of one to the other is what people alter to achieve a certain result. For example, lowering carbs and fats while amping up on protein is what body builders do to gain more muscle. Runners will lower protein while increasing carbs to give themselves a rush for a big races.
