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. This test is used to distinguish starch (polysaccharide) from carbohydrates. Reaction between starch and Iodine produce a dark grey, black color and it means that the test is positive. A yellow color means that test...

Pre-lab: Identifying Carbohydrates

Analysis: Lab 1 Identifying Carbohydrates There were many ranges of color changes in the Benedicts test and Iodine stain. For the Benedicts test, this oxidation/reduction response changes the arrangement of the reducing sugar creating a colored precipitate. The change in color is correlated to the first concentration of the reducing sugar. For the iodine test, the three dimensional structure of various polysaccharides permits them to react with the iodine stain to produce a certain color. As far...

Carbohydrates, Protein, Lipids, and Dna

Carbohydrates have two major functions in plants and animals: they serve as fuel and building material. Plants store most of their energy in the form of starch. Starch is a polysaccharide (consisting of several conjoined sugars). Synthesizing starch enables the plant to stockpile surplus glucose, and since glucose is a major cellular fuel, starch represents stored energy. The sugar can later be withdrawn by hydrolysis, which breaks the bonds between monomers. Animals, in turn, have enzymes that...

Lipids Cells come to a point where they have to store all their long-term energy in some biological molecules; a group of organic compounds are classified as lipids. These are molecules made mostly from carbon and hydrogen atoms. Lipids contain the same elements as carbohydrates: carbon, hydrogen and oxygen. They solute in nonpolar organic solvents, or basically they don’t solute in water. This is because they are hydrophobic and contain a tail, which is nonpolar and repellent to water. Lipids...
