Chemical Tests of
Biologically Important Molecules
A standard lab found in nearly every introduction to biology course. Students are introduced to the use of Benedict's solution, iodine, sudan IV, Biuret, and dische diphenylamine solution to identify simple sugars, polysaccharides, lipids, proteins, and nucleic acids. This lab was written to be as clear and concise as possible for an introduction to biology level student.
Essential concepts: Macromolecules, organic molecules, monosaccharides, disaccharides, polysaccharides, amino acids, proteins, lipids, nucleic acids, Benedict's solution, iodine, Biuret, dische diphenylamine, Sudan IV, positive control, negative control.
