Chapter II Review of Related Literature Chemical Wood Pulping Chemical wood pulping involves the extraction of cellulose from wood by dissolving the lignin that binds the cellulose fibers together. The 4 processes principally used in chemical pulping are kraft‚ sulfite‚ neutral sulfite semichemical (NSSC)‚ and soda. The first 3 display the greatest potential for causing air pollution. The kraft process alone accounts for over 80 percent of the chemical pulp produced in the United States

Laboratory Exercise #3 Measuring Protein in Solution Abstract The purpose of this lab was to learn about the Biuret assay reaction to determine if it can detect proteins and amino acids; also‚ to understand the process of “salting out” proteins and how to determine the amount of protein in a solution. In order to do so‚ egg white and ammonium sulfate were mixed on ice and then put into the centrifuge. After PBS was added‚ the amount of protein could then be determined. After that‚ 14 test tubes

of Muscle Proteins to Infer Evolutionary Relationships of Mammals‚ Fish and Birds Abstract This experiment used electrophoresis to examine the makeup of muscle proteins from two mammals (cow‚ Bos taurus; bear‚ Ursus americanus)‚ two aves (chicken‚ Gallus gallus; turkey‚ Meleagris gallopavo)‚ and two fish (King Salmon‚ Oncorhynchus tshawytscha; Albacore Tuna‚ Scombridae unclassified). The hypothesis was that as species have diverged evolutionarily‚ the makeup of their muscle proteins has also

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 the protein concentration
