Lab Two; Chromatography of Food Dyes Jan Konig 28.04.2013 11:00am Chemistry 121‚ section DE Abstract: The second lab deals with the chromatography of food dyes which means you figure out what kind of compounds are used in a product like food color etc. by comparing the result to FD&C Food Dyes. You use six different food dyes‚ four food colors out of the store‚ two different Kool Aid powder and four different colors of candy like M&Ms you use for the chromatograph. At the end you try

Participant Obvservation Sociology is the systematic study of humans in groups. There are different ways to study these groups of humans and most sociologists are aware of the different ways. As a student studying sociology the class was given a task to observe human interactions in groups and relate what I found out to what I have learned so far. Out of the many different ways to study groups we had to use participant observation‚ systematically studying people while joining them in activities

In biology‚ there are four major biological macromolecules that are found in the cell‚ carbohydrates‚ lipids‚ nucleic acid‚ and proteins. Biological macromolecules are also known as organic molecules. Biological macromolecules are very large molecules that are of a key importance to living organisms. Most biological macromolecules are built by joining smaller molecule subunits. Carbohydrates are large groups of organic compounds found in foods such as sugars‚ starches‚ glucose‚ fructose‚ galactose

With macromolecules‚ your body will be bigger‚ better‚ faster‚ stronger‚ and built to last longer! There are four major macromolecules that can give you more energy‚ strength‚ and enough fat to keep you warm and protected. In conclusion‚ the four major macromolecules are important to growth and development because they produce and store energy‚ create muscle to build a repair the body‚ create fat when it gets cold‚ and to tell when to release amino acid to build certain protein. Macromolecules are

test can be done for testing these sugar to show or prove are they reducing sugar or non reducing sugar.Example of the test that can be done is Benedict test. 1 In plant‚glucose is stored as the polysaccharide starch.Example of food that rich in starch is oat‚cereal‚rice and corn.Starch can be divided into two groups which is that is amylose and amylopectin. Natural starches are mixtures of amylose

Understanding the macromolecules in our bodies that are essential to our lives is what makes up molecular biology. One of the many things to understand about the macromolecules in our bodies is to first know about how they interact and types of interactions that are involved with each other‚ especially down to an atomic level. These interactions are included within types of covalent and non-covalent bonding. Covalent bonding involves the pairing of electrons that are shared between atoms‚ whereas

05/14/2013 7.1 Lab Report- Caloric Content of Food TITLE: LAB 7.1 CALORIC CONTENT OF FOOD PURPOSE: In this lab we will have the opportunity to measure the energy in a variety of foods‚ by heating/burning a portion of the food item and catching the heat released into a known mass of water in a calorimeter. We will also identify units of measuring heat such as calories and joules. We will use basic lab equipment provided in our labpaq and we will use several household items as well. We
