Biology 100 Lab Laboratory Report Title: Identifying the four major classes of macromolecules through various tests. Group Members: Antonia Johnson‚ Payton Ewing‚ Lenneisha Hepburn‚ Kendisha Hanna‚ Introduction: Macromolecules also known as biological molecules are monomers which are the simple units of polymers. All macromolecules contain carbon and hydrogen which are found in organic compounds. In this Experiment we will test for the presence of protein‚ starch‚ lipids‚ and sugars by analyzing

EFFECTIVENESS OF BASIL ( Ocimum Basilicum Lamiaceace ) PLANT FOR URINARY TRACT INFECTION INTRODUCTION Background of the Study The care of Urinary Tract Infection (UTI) is a common costly problem in acute care and home care population. Many therapies have been made for the treatment. Despite this‚ the patient still suffer from pains when urinating and the financial burden. In the locality‚ Urinary Tract Infection was commonly experienced among teenagers due to lifestyle and diet. Nurses in the community

In our experiment‚ we will be testing three different proteins to see if they denature at the same temperature. A protein is a molecule containing amino acids created in ribosomes that have many functions‚ including being an enzyme and transporter‚ structuring‚ translating genetic information‚ and serving as a channel for charged molecules to pass through the cell membrane. As a molecule‚ a protein is shaped like a coil (Food Science Basics 2014). Denaturation is when a protein’s shape changes due

products‚ commercially produced milks and eggs were sampled. Chicken eggs were sampled from Dhaka and its nearby other seven districts covering the central region of Bangladesh. Dhaka‚ Narsingdi‚ Kishoreganj‚ Mymensingh‚ Tangail‚ Gazipur‚ Narayanganj‚ and Munshigonj were selected for the study. Twelve eggs were randomly sampled from each district’s egg stock market. In Dhaka‚ Gazipur‚ and Tangail’s market both brown and white colored eggs were found. Six eggs from each type were sampled from these three

Title: Benedict ’s test for Reducing Sugars Testable Question: Are all carbohydrates reducing sugars? Hypothesis: If the carbohydrate contains available ketone or aldehyde molecules then they are reducing sugars. Variables: a. Independent: Function groups react w/ reagent b. Dependent: Color change (red‚ orange‚ yellow) Control: Water Materials: - 4 mL of each solution (Water‚ Starch‚ Glucose‚ Maltose‚ Sucrose‚ Onion Juice‚ Potato slice‚ Milk) - 8 test tubes

conditions the coagulation process may be reversible. (Campbell‚ et.al‚ 1979) 4A.2.2 Chemistry behind Coagulation Ovalbumin the main protein in egg white is a globular protein denatured by heat‚ this means reaction is more rapid with an increase in temperature of heating. Since heat is absorbed during coagulation of egg proteins‚ the reaction is endothermic. Egg white coagulated by heat changes from a transparent viscous solution to a opaque white gel‚ the water of white trapped by the protein. (De Mann
