Total Carbohydrates Using the Phenol-Sulfuric Acid Method

The standard curve of the unknown glucose solution was constructed in order to solve for the concentration of glucose in corn syrup and Gatorade samples. These calculations can be shown in the results section of the lab. Under proper conditions, the phenol-sulfuric method is accurate to ± 2% (Nielson 2010). This seems to be true with the %CV shown in Tables 2 and 3 in the Absorbance columns. However, the accuracy of the results is completely dependent on the accuracy of the standard curve. If the standard curve were to be inaccurate, then the findings of the concentration of corn syrup and glucose would also be inaccurate. When comparing the labels of the samples, corn syrup contains 31 g sugar/…

The Iodine Test sor Starch

The purpose of this experiment was to use Iodine, Benedict and Biuret to test the reaction of the following 12 samples: 1% glucose, 0. 3% glucose-1-phosphate, 1% maltose, honey, 1% sucrose, 1%lactose, 1% glycogen, 1% starch, protein, beer, distilled water and an unknown solution (test tube: 300). The iodine test for starch was to test how would starch reacted if we put iodine in it. The color of starch before the test was clear. The color of the iodine was brown. When you added iodine into starch, the result was the starch solution turned dark blue. Starch had a positive result is because of the complex of iodine stuck inside the amylase coil which produced a characteristic purple – black…

Carb Cutter

Many Americans have turned to diet pills. Should you? In the United States today many people have supposedly lost weight with certain pills. One of these pills is called carb cutter. Carb Cutter claims to inhibit the activity of the starch-digesting enzyme, amylase. When the diet pill binds to the amylase, it prevents the breakdown of starch. In the Biology 1103 lab, we conducted two experiments to determine whether or not the diet pill, Carb Cutter, actually worked. In each experiment we used an experiment tube and a control (blank) tube. The purpose of a blank is to set a base level (zero) from which other measurements can be performed. In the first experiment we were trying to see if…

Care for the physical and nutritional needs of babies and young children

When planning meals for young children it is best to meet their nutritional needs. Each meal should be the right consistency for the child and include all of the major food groups. There are five food groups, bread, cereals and potatoes (starchy food), fruit and vegetables, milk cheese and yoghurt, meat, fish eggs, beans, lentils (protein) and foods high in fat and sugar. When planning a meal the fruit and vegetables should be served at each meal and should try and have five servings of either each day. Milk cheese and yoghurts should be served three times a day and bread and cereals either as a snack such as bread sticks or as an accompaniment to a meal. Meat, fish…

Kamote tops

Sweet Potato Leaves (talbos ng kamote) Sweet potato tops (kamote tops or talbos ng kamote) are the shoots and leaves of the sweet potato plant that contains protein, lipids, carbohydrates, calcium, iron, phosphorus and vitamins A and C. It is excellent source of anti-oxidative compounds, mainly polyphenolics, which may protect the human body from oxidative stress that is associated with many diseases including cancer and cardiovascular diseases. It is relatively low in calories and has no fat and has the highest content of total polyphenolics among other commercial vegetables studied. Studies also indicate that it can also be used as a cure for diabetes particularly the purplish form. Research also shows that the nutritional content of kamote tops or sweet…

What organic molecule can be detected with Lugol’s?

When we put the Lugol’s regent (I2Kl) in the beaker, we can observe the effects of osmosis as the Lugol’s regent (I2Kl) solution on the outside of the beaker permeates the intestine (Dialysis tubing) inducing a chemical reaction that will turn the liquid in the intestine (Dialysis tubing) blue-black. If the amylase successfully digests the starch, what results would you expect? If the amylase successfully digests the starch, I would expect a no color change occur as well as a presence of glucose in the intestine (Dialysis tubing). If the amylase only partly digests the starch, what would you expect to happen? If the amylase only partly digests the starch, I would expect to see a faint color change as…

Read Speech

Breakfast It Is! Have you ever worried about the grumbling of your stomach in a classroom in the morning? Have you ever thought about getting snacks or lunch in the morning because of intense hunger? Are you like those who hop out of bed each morning ravenous and ready for breakfast? Or do you get through the morning with just a hot cup of coffee and absolutely no interest in that first meal of the day? Breakfast plays a very important role for our health, but a lot of people neglect breakfast. It always surprises me when I hear someone who skip breakfast in an effort to cut calories and lose weight, or because they’re convinced that they are not…

Adkins or Fadkins Case Study

Proteins – Proteins are chains of amino acids. In general, proteins may be structural proteins used to build tissues, they may be enzymes that mediate chemical reactions, or they may be hormones. Examples of proteins would be channel proteins in cell membranes, collagen protein in the skin, actin and myosin in the muscles, and hemoglobin in red blood cells. Types of dietary sources would be, meat, milk, (both of which are not pure proteins, but are good sources of protein), eggs, grains and beans. Carbohydrates – Complex carbohydrates are chains of simple sugars. Their primary role in animals is to provide energy. Plants use starch as an energy storage molecule, and use complex carbohydrates such as cellulose for support. Examples…

Testing for the Presence of Starches

To test for the presence of starches and protein macromolecules, to introduce the concept of variations in chemical compounds. Hypothesis: If biuret is blue after a test for protein, then it is a negative result because biuret reagent is blue to begin with. If a solution is pinkish purple, or purple, then the test for protein is positive. The test solution for starches is yellowish brown. If any substance that is yellowish brown when mixed with iodine, then the test for starches is negative. If the solution turns purple, or a dark purplish black, then the test for starches is positive. If DI water, and sucrose are tested for proteins using biuret reagent, then they will show a negative result….

Mood Swings

Have you ever felt that feeling when you hate every single thing around you? Or the feeling that even someone breathing can annoy you? And lets not forget that feeling when you’re just sad and you just feel so empty, for no apparent reason? Well, being a girl it kind of comes naturally being hormonal and all at that certain time every month and no it doesn’t immediately mean that were bipolar. But, not only girls experience these kinds of hormonal activities even boys do. Studies show that everyone can experience mood swings due to the daily factors in our lives like stress, for girls PMS, sometimes even the food we eat, sudden changes and many other factors. Needless to…

The Food Dilemma of the Omnivore

Everybody loves food, especially America. Americans are obsessed with food, and that is correlated to the fact that in America, food is almost always readily available to us. We have fast food restaurants, grocery stores, restaurants, and farmers markets with most of the food being relatively affordable. Our nation without a doubt has many dilemmas that need to be solved, however if you were to group all of these dilemmas into different sets and focus on the “food” set of the dilemmas, which would be our nation’s current food dilemma? Taking everything into account, finding healthy, tasteful foods seems to be the main concern of many Americans today. With obesity on the rise like it is, healthy foods are a…
