BIOL 130 Lab Report Identifying Two Macromolecules - Carbohydrates and Proteins 9/26/2013 [Type the company name] INTRODUCTION As the name suggests‚ macromolecules are large molecules that make up more than 90% of the total cell mass. These biological macromolecules vary greatly in size - from several hundred to several hundred million molecular weight units - and are made up of monomer units. There are four major classes of biological macromolecules: proteins‚ carbohydrates‚ lipids‚

Experiment 3: Evaluation of Gas Constant Purpose: The purpose of this lab is to demonstrate the ideal gas law under ordinary conditions. In this lab‚ the variables in the ideal gas law are known or can be found aside from the constant R. Thus‚ the R values can be found and relatively determine the relevancy of the ideal gas law to the lab conditions. The ideal gas law was tested using the reaction: Mg (s) + 2HCl2 (aq) H2 (g) Procedure: 1. Ribbons of magnesium (5) were cut to the approximate

Macromolecules Lab Purpose: to determine a method of testing for macromolecules. Materials: Knowns: Unknown: Test Solutions: Glucose solution Unknown solution Iodine solution Gelatin solution Benedict’s solution Starch solution Biuret solution Oil Brown paper Water Procedure: 1. Create a data table. 2. Label 5 test tubes with known solutions. 3. Add 10-20 drops of each known solution to respective test tubes‚ do not mix pipets! 4. Add 3-5 drops of

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

The “Beats for life” study provides an individual with results that the environment one surrounds themselves in has a significant impact to his or her heart rate. The neutral environment gave the participants no stimuli. This caused the heart rate slightly increase or decrease by less than 1.00 bpm. It is also possible that the heart rate of the participants had no change. The stressful environment presented multiple stressful and discomforting stimuli. These stimulates caused the heart rate

Organic molecules are the molecules of life that include Carbon and Hydrogen. Organic molecules consist of four important classes which are lipids‚ carbohydrates‚ proteins and nucleic acids. The most important organic molecule is Carbon. Carbon can form with up to 4 different atoms to form chains‚ rings and branches. Organic molecules also contain monomers. Monomers are the “building blocks” of macromolecules. Macromolecules are made up by chains of monomers‚ these are called polymers. Continuing

This experiment had four parts to it‚ where you had to find out if the food you picked contained starch‚sugar‚lipids and protein.The food item that was chosen to decipher was a Big Mac and you chose what from the burger you wanted to test to see what it was made of‚ example like the bun of the burger. When testing you would have one test tube of water with food and the other test tube with the solution needed and food.The reason for the test tube with the water is because it was the indicator. If

plants and animals too. Because we know about these macromolecules‚ we can better understand the world around us. They play a vital role in keeping us healthy and aiding in the diagnosis of medical conditions‚ they are responsible for what keeps us running and they are vital in even the tiniest forms of life; cells. Cells are the building blocks of everything around us and without cells and these essential components of life there would be no life. The benedicts reagent test was designed to expose

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

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
