Biological Molecules
Introduction:
In this experiment, simple chemical tests will be performed to identify the presence of various types of biological molecules. These tests take advantage of the fact that different types of molecules have different functional groups and, therefor, different chemical properties. Thus, they will react to test reagents (also called indicators) differently.
Materials: Biuret, Sudan III, Iodine, Benedict, water, hot plate, paper towels, pipette, ruler, goggles, and a timer.
Method:
Benedict’s test for reducing sugar:
1. Ruler was used to mark 1 cm and 2 cm marks on each tubes.
2. Negative control tube was filled with 1cm of water. Positive control tube
