EXTRACTION AND CHARACTERIZATION OF PROTEINS Abstract Different techniques and principles for protein extraction and characterization were demonstrated in this experiment. Various proteins were extracted from different sources: 1.67 g yeast invertase‚ 1.03 g egg white albumin‚ and 5.15 g of milk casein. Activity assay for invertase was performed using Benedict’s test and the enzymes inverting action on sucrose was confirmed. Warburg-Christian Method and Bradford Assay were also employed to determine

coffee. The average pure caffeine yield was 0.330% with a standard deviation of 0.179. This yield is slightly higher than the yield of this report because of the error that occurred during the experiment. A small amount of coffee from the first extraction was stuck in the nozzle of the separatory funnel so it was removed with a pipet and then decanted. This resulted in a loss of product. The average impure caffeine yield was found to be .948% with a standard

Lab 4: Photosynthesis and Chromatography of Spinach Leaves Discussion: The chromatography of the spinach leaves was taken to establish what pigments were present in the chloroplasts of the leaves. The solvent carried and separated the different pigments up the cellulose paper. The solvent moved up the paper because of capillary action because of adhesion of the solvent molecules and the paper. The pigments dissolved in the solvent also were carried up the paper and were separated because
