Testing for the Presence of Lipids‚ Proteins‚ and Carbohydrates in McDonald’s Menu Items Emma Heironimus‚ White 3 There are four main macromolecules; proteins‚ nucleic acids‚ lipids‚ and carbohydrates. The presence of some of these‚ such as sugar‚ fat‚ starch‚ and protein‚ can be determined using tests such as Benedict’s solution‚ Lugol’s iodine solution‚ Biuret’s reagent‚ and Sudan III. Control tests were performed to determine what a positive result would appear like. Then the tests were performed

*What is Biochemistry?* * Biochemistry also known as Chemistry of life is the study of chemical substances and vital processes occurring in living organism. Biochemistry governs all living organisms and living processes. * Study of chemical processes in living organisms‚ including‚ but not limited to‚ living matter. * Biochemistry is the science dealing with the chemical composition and chemical reactions happening within‚ and between the living cells of all organisms. → The

They are also used in building macromolecules‚ most of the glucose is absorbed and is used to make energy‚ however‚ some glucose is converted to deoxyribose and ribose‚ these are essential for the building up of macromolecules such as DNA‚ RNA and ATP. Carbohydrates are also used for lipid metabolism. Nonetheless‚ despite of the fact that carbohydrates have many positive effects

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

(Choose one answer.) * Proteins are found inside the cell‚ because proteins are a macromolecule. 5.

CHAPTER 1 INTRODUCTION: THEMES IN THE STUDY OF LIFE OUTLINE I. Life’s Hierarchical Order A. The living world is a hierarchy‚ with each level of biological structure building on the level below it B. Each level of biological structure has emergent properties C. Cells are an organism’s basic units of structure and function D. The continuity of life is based on heritable information in the form of DNA E. Structure and function are correlated at all levels of biological organization F. Organisms are
