Carbohydrates are compounds having an empirical formula of (CH2O)n that are commonly referred to as sugars and starches LAB REPORT Introduction All living things contain organic molecules such as lipids, carbohydrates, proteins and acids. In order to detect the presence of carbohydrates, proteins and lipids we have to do experiments. The Iodine test is used to detect the presence of carbohydrates Distilled water gave negative test because it is not carbohydrate. A large apple has around 28-31 grams of carbohydrate. Apple and cabbage contain carbohydrate so that they gave purple ring in this test.

Part C. Tests for Lipids (Brown Paper Test) Lipids are nonpolar molecules with a variety of structures. They do not dissolve in water, which is a polar substance. Lipids include the fats, the oils, the sterols, and the waxes. Very common lipids are the triglyceride fats that are composed of glycerol and three chains of fatty acids Purpose: The purpose of this lab was to test for sugars, starches, proteins, and lipids. Background information: Biological macromolecules are the large molecules necessary for life. There are four different types of macromolecules which include carbohydrates, lipids, proteins, and nucleic acids Qualitative Test for Carbohydrates: Most of the tests of the carbohydrates are based on their reducing properties (due to the presence of reducing aldehyde or ketone groups). Fehling's test, benedict's test are the example of this. The unspecific Molisch's test for carbohydrates is one of the examples of some tests which are based on the.

Lipid removal. The food sample to be analyzed is therefore dried, ground to a fine powder and then the lipids are removed by solvent extraction. Protein removal. Proteins are usually broken down and solubilized using enzymes, strong acid or strong alkali solutions. The resulting amino acids are then separated from insoluble fiber by filtration. This lab uses four tests to identify the presence of simple carbohydrates, starch, proteins, and lipids in foods. Respectively, those tests are Benedict's test, Iodine test, Biuret test, and Sudan III test. Benedict's solution is made up of copper (II) ions, which react with all monosaccharides and most disaccharides Benedict's Test is used to test for simple carbohydrates. The Benedict's test identifies reducing sugars (monosaccharide's and some disaccharides), which have free ketone or aldehyde functional groups. Benedict's solution can be used to test for the presence of glucose in urine. Some sugars such as glucose are called reducing sugars because they are capable of transferring hydrogens. In today's lab we will test for factors that affect carbohydrate digestion, protein digestion, and fat digestion. We will also run tests to learn how surface area affects the rate of digestion. We will use chemical indicators to test for the presence of polymers (before chemical digestion) and monomers (after chemical digestion)

A change in color, or other physical characteristic usually indicates the presence of a particular Bio 2402 Lab Data Sheet Control Tests: Write out your. Substances called indicators can be used to test for the presence of organic compounds. An indicator is a substance that changes color in the presence of a particular compound. In this investigation, you will use several indicators to test for the presence of lipids, carbohydrates, and proteins in various foods. CARBOHYDRATES Milk is a colloidal aqueous suspension consisting of many components, several of which include carbohydrates (sugars), lipids (fats), proteins, and phosphate. The percentage of each of these components will depend upon the source of the milk ( e.g., cow, goat, etc.) as well as the methods used to process the milk

There are several types of biological macromolecules: Carbohydrates, Proteins, Lipids and Nucleic acids. All macromolecules, except lipids, are polymers. A polymer is a long molecule composed of chains of monomers. Monomers are small molecules that serve as building blocks of polymers. In addition, there are also oligomers in nature In this laboratory period you will learn about different classes of organic compounds by doing chemical tests for lipids, carbohydrates, and proteins.
