I. Abstract The common organic compounds provide us with nutrients are sugars and starches‚ carbohydrates‚ proteins‚ and lipids. In this lab‚ qualitative tests are performed to identify the presence of organic compounds in food using indicators‚ chemical substances that react in a certain way when a particular substance is present. We put one indicator into the each test tube containing different solutions at a time to see what organic compound is present. The color change in the indicator tells

If you want your body to function correctly you have to have three different food types in your diet. You should have electrolytes‚ carbohydrates‚ and protein. These can be found in your favorite foods you eat every day. Human’s need these three food types for our body’s to function properly. What do electrolytes do to help our bodies?(Copyright © 1998-2015 HowStuffWorks) Electrolytes are important because they are what your cells (especially nerve‚ heart‚ muscle) use to maintain voltages across

Dr. John Sievenpiper‚ a professor at the University of Toronto who specializes in medicine‚ is a vocal critic of the anti-fructose group. His main argument is that there is no unique harm from fructose when calories remained the same or added to a controlled diet and the link to overweight obesity and diabetes. His findings or premise is that although biochemistry has shown that fructose is metabolized differently than glucose and could potentially promote fat and weight gain‚ the argument needs

the major types of organic compounds in living organisms ‚ several biochemical test were used . Introduction Organic molecules are those primarily made up of carbon‚ hydrogen and oxygen. The common organic compounds of living organisms are carbohydrates‚ proteins‚ lipids‚ and nucleic acids. Each of these macromolecules (polymers) are made of smaller subunits (monomers). The bonds between these subunits are formed by dehydration synthesis. This process requires energy; a molecule of water is removed

One study found that drinking tea all day improved alertness and performance just as well as coffee and was less likely to disrupt sleep. Combine protein with good carbs. Snacks that include an ounce or two of protein with some complex carbohydrates give you a quick energy boost — without an energy crash a few hours later. Give these tasty pantry combos a try: • Small pop-top can of salmon or tuna with whole grain crackers • Small box of raisins or dried cranberries with a handful of nuts

fats‚ carbohydrates‚ and proteins and the other three nutrients- water‚ vitamins‚ and minerals aid in the body’s use of energy. The textbook provided with good examples of these nutrients and I found it very helpful. Let’s start on carbohydrates in the book. The textbook mentions that carbohydrates are the body’s primary source of energy for all body functioning. Includes chemical compounds sugar‚ starches‚ and dietary fibers. For some reason‚ I never knew that sugar was part of carbohydrates‚ I thought

Purpose: To use indicators to test for the presence of organic compounds in certain substances. Hypothesis: Honey will contain sugars‚ egg white contains proteins‚ corn oil contains lipids‚ oats contains starches and proteins‚ gelatin contains sugars and proteins‚ potatoes contain starch‚ and apple juice contains lipids and sugars. Materials: 9 test tubes Test tube rack Test tube holder Grease pencil Hot plate 20 ml honey solution 20 ml egg white and water mixture 20

green precipitate means a little glucose was present. A red precipitate means glucose is present in vast amounts. Food Test 2: Test for Starch – with Iodine solution. Iodine solution is used to identify the presence of starch- a complex carbohydrate. Iodine solution (potassium iodide solution) reacts with amylase – a type of starch – whereby a blue-black polyiodide complex is formed. Method 1) Mix smalls amount of each food samples (i.e.‚ Egg lumen‚ cylindrical piece of potato tuber‚

Biology Laboratory Report Practical 4 Food tests Introduction The main components of food are proteins‚ fats‚ carbohydrates‚ and‚ of course‚ water. Proteins‚ lipids and carbohydrates are carriers about energy necessary for vital activity. They are a plastic material for the formation of structures of the body‚ as well as used for the synthesis of hormones and substances that transmit signals in the nervous system. Our food also includes food (plant) fibers‚ has recently seemed unnecessary ballast
