Hailie Armstrong Ms. Gorges U4 L8 Chemistry 11/19/14 Modeling Molecules Introduction: You can represent a molecule two-dimensionally‚ as a structural formula or electron dot structure. Although such models are useful in certain contexts‚ they do not accurately represent bond angles between atoms or shapes of molecules. In this activity‚ you will construct three-dimensional models of several molecules. You will use electron dot structures and structural formulas to inform how you construct the

I can travel through the pipes into my kitchen faucet. I have many uses. I can be hot‚ warm or even cold. I can be mixed with dish soap in the kitchen sink or ran through a dishwasher to clean the dishes. I can wash clothes or be used to cook with. I can be mixed with something or drank plain. There are a lot of foods made with me. I am used

THE CHEMISTRY OF ORGANIC MOLECULES I. MACROMOLECULES-large molecules that are composed of smaller molecules and atoms that are bonded together. These are among the largest of all chemical molecules. A. Polymers-the largest of the macromolecules. These are composed of numerous‚ small identical subunits known as Monomers. There are 4 major polymers that are important for living organisms. These polymers are; carbohydrates‚ lipids‚ proteins and nucleic acids. B. Polymers

Abstract This experiment aimed to study the effect of various denaturants on albumin and casein protein extracts through viscosity measurements. 5 mL samples of native and denatured protein solutions were prepared‚ using -mercaptoethanol‚ urea and SDS as denaturants for albumin‚ and NaOH‚ NaCL‚ HCL‚ -mercaptoethanol‚ urea and SDS for casein. 5 mL blank solutions for each denaturant used were also prepared. The viscosity of the solutions were determined using Ostwald viscometer. ________

Discovered in 1838‚ proteins are recognized as a large number of superior organic compounds that make up living organisms and are essential for their functioning. In other words proteins are the building blocks of life. They do many tasks for the human body and other organisms‚ that could not be done individually. These macromolecules could function as structural proteins and form structures such as keratin in hair‚ teeth‚ bones‚ muscles‚ collagen in connective tissues‚ horns in animals

nDescribing food Describing food is not as easy as it would seem. How many ways can you say something was really tasty? Not enough to keep you interested in what you are writing. That is why we have to borrow words from other areas to describe the food and the effect it has on us. You can compare a dish to a picture‚ a sports game‚ a musical performance or give it personality. Describe its sunny or somber mood‚ shyness‚ assertiveness‚ or contradiction of flavors. Knowing the words for describing tastes and

Denaturing of Proteins Research Paper Abstract: Introduction The experiments the objective is to determine‚ the possible measures of the denaturation process of several proteins by using a home based temperate The necessary applications of this experiment are to compile all the possible measures of the denaturation process in understandable units and explainable means. Other methods possible for research are by using a
