Problems and Objectives:
The purpose of this lab was to select the suitable test for an organic molecule and define the safe process for that test. An organic molecule is normally found in or produced by living systems. (Unknown Author, 2014, this lab one was supposed to infer the results of the test and be able to identify if major biomolecules are present. You were to analyze a variety of tests including analyzing a glucose solution for the presence of simple reducing sugars, analyzing a sample of vegetable oil for the presence of lipids, analyzing a sample of gelatin for the presence of protein, and analyzing an unknown sample to determine the presence of starch, simple reducing sugars, lipids, and proteins through chemical tests. (Packet, Crafton 2014) Background:

Molecules are two or more atoms bonded together to make one system. Most of the common molecules in living organisms fit in four classes of carbon containing molecules, which are carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates occur in foods and living tissues, and contain hydrogen and oxygen with the same ratio as water. The ratio 1:2:1. Lipids are basically fats. They are unable to be dissolved in water or any liquid but can dissolve in organic solvents. The configuration of cells are composed of a variety of chemical molecules. Cell metabolism involved the construction and obliteration of numerous diverse sorts of molecules. (Packet, Crafton 2014) Proteins are highly varied organic molecules establishing a large percentage of the mass of every organism. Proteins are an essential nutrient in the diet of animals and other non-photosynthesizing organisms. Lastly, nucleic acids are long macromolecules, can be DNA or various types of RNA. DNA stands for deoxyribonucleic acid and they transfer genetic information. RNA stands for ribonucleic acid, and it is complimentary to the DNA strand. RNA...
