Mazarei Food Microbiology April 22‚ 2011 Purpose: To test the pH level of many common household object by use of the juice from a red cabbage. Background: pH is the measure of the acidity or basicity of a solution. The pH scale ranges from 1 to 14 with 1 through 6 being acidic and 8 through 14 being basic; 7 is considered neutral. The use of the red cabbage‚ or red cabbage juice is because red cabbage can be used as an acid/base indicator. The pH level of foods is important to food microbiology

In this lab activity students performed an experiment with the use of distilled water and baking soda solutions as control. The experimental controls are accuracy indicators of laboratory results. Thus‚ controls are important in a lab because the observation results are dependent on the controls. The experimental results can be determined to be valid when it is compared with the control solution. The higher the similarity between the results and the control solution‚ the more accurate the investigation

A Macromolecule is a molecule with a very large number of atoms .The word macromolecule is usually used for describing polymers. Molecules that are made up of smaller molecules are called monomers‚ there are also Organic Molecules composed of carbon atoms .The functions of the Four big Macromolecules: First‚ Carbohydrates‚ carbohydrates is the function of being used for energy production during cellular respiration. Second ‚ Lipids‚ lipids are used for four things; insulation and long-term energy

Identification of Macromolecules Introduction The purpose of this lab is to test for the presence of macromolecules in various foods. Tests are performed to describe the basic structure of proteins‚ lipids‚ glycerides‚ and carbohydrates. We are to recognize the positives and negatives in these macromolecules. Also we are to identify the roles that proteins‚ lipids‚ minerals‚ vitamins‚ and carbohydrates play in the body’s construction and metabolism. Procedure / Results 5.1 Carbohydrate

Macromolecules are molecules that are large and essential for life. They consist of carbohydrates‚ nucleic acids‚ proteins‚ and lipids. Carbohydrates are molecules that are composed of monosaccharaides. Carbohydrates include cellulose‚ starches‚ and sugars. Two tests may be used to determine the presence of the carbohydrates. Those tests are the Benedict’s test and Lugol’s Iodine Test. Proteins are another category of macromolecules. The protein is a type of macromolecule that carry out many processes

Wilson Grand Canyon University Professional Research Project NRS-441V March 19‚ 2013 Identifying a Problem The clinical environment that I previously worked in was a correctional institution. During the time that I worked in corrections I encountered several inmates that had HIV. It was this environment and the experience that I received this idea and it is what gives me the inspiration to build a proposal for change. Within this system is where I discovered
