Analyze Macromolecules

Unknown biological molecules can be correctly identified using various tests, including colorimetric chemical tests. Colorimetric tests are when a chemical reagent, such as Benedict’s, is used on a substance or solution and a certain color change occurs as a response. Carbohydrates and proteins, two of the larger types of biological molecules, also called macromolecules, are actually chains of molecules called polymers. The smaller molecules that build up these chains are

We decided to do the McMush Lab. The lab was designed to see the biomolecules inside an average McDonald’s Happy Meal. We decided to use a meal we have all had and to see what we were eating. Our results showed certain biomolecules.

All living things contain some form of organic macromolecules including: Lipids, proteins, carbohydrates and nucleic acids. All of these organic molecules are alike in the sense that is they are made up of bonded elements such as carbon, hydrogen, oxygen, and to smaller quantities nitrogen, phosphorus and sulfur. The macromolecules each contain large long chains of carbon and hydrogen atoms and often consists of repeating smaller molecules bonded together in a repeating pattern (polymers). To test whether a specific solid white substance is a protein is simple due to the unique chains found in the respective type of macromolecule. To test if the substance is a carbohydrate, two tests could be performed on separate samples of the object. First,

The most common macromolecules found in living organisms are lipids, carbohydrates, proteins and nucleic acids. Briefly, the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy, information and much more. Most foods are known to be combinations of macromolecules. While some of these compounds can be detected by taste tests, many cannot. Scientists then use certain tests to determine the presence of macromolecules.

Dehydration-synthesis is a reaction that occurs to form different types of macromolecules. It is a reaction that leaves a macromolecule structure along the lines of developing its own specific function in a living organism. The 4 most common ones are carbohydrates which includes monosaccharides and polysaccharides, lipids, proteins and nucleic acids (Mack 2012). Scientists identify different types of macromolecules to achieve a better understanding on how they function in our bodies. This can be achieved by studying their chemical properties and structure.

1. Carbohydrates: Are Molecule composed of carbon, hydrogen, and oxygen, and they include sugars and starches.

Introduction: In this lab, we studied biomolecules. Biomolecules are molecules that are existent in all living organisms. The four biomolecules, we are learning in class are proteins, carbohydrates, lipids, and nucleic acid. The three biomolecules being addressed in the lab are proteins, carbohydrates, and lipids.

Enantiomers are two same chemical moieties which have a different spatial arrangement. They are described as mirror images of each other, that is they are non-superimposable. They have similar physical properties but differs in some chemical properties. The two different arrangements are classifieds as L- and D-, depending upon the functional group of reference.

Purpose: To study and investigate the presence of macromolecule in different types of solutions and the unknown solution of macromolecule. Introduction: Macromolecules are polymers that are made up of monomers which combine into long chains called polymers (Alberts, 1998). This experiment was conducted to test the presence of a few macromolecules in many different solutions. Carbohydrates, lipids, proteins and nucleic acids are the four most well-known macromolecules found in living things.

There are four main macromolecules also known as polymers. The four macromolecules are protein, carbohydrates, lipids and nucleic acids. "The first three are the three macromolecules that are consumed. "-1 In this lab we use two carbohydrates, protein and water.

The type of bio-macromolecule that is an enzyme is a protein. The three factors that affect the tertiary structure of a protein is the primary sequence of amino acids, the different kinds of bonds involved in the structure, and different charges of the amino acids. When a protein is denatured, all the non-covalent bonds break apart and release energy. This loses the shape and function of the protein.

Biological macromolecules are the large molecules necessary for life. There are four different types of macromolecules which include carbohydrates, lipids, proteins, and nucleic acids. Each macromolecule has a specific function like providing energy or simply insulation. Macromolecules are made from monomers which come together through dehydration synthesis or hydrolysis to create the polymer or macromolecule.

Three of the four main classes of macromolecules, lipids, carbohydrates, and proteins, were identified in five unknown substances. Then, using the results from the tests, noting which unknowns contained which macromolecules in which amounts, the results were cross referenced with the nutritional labels of various foods. Using the process of elimination and deduction, the unknown substances were matched to a specific food item.

The objective of this experiment is to identify macromolecules by examining the chemical changes and analyzing the results based on the properties of known solutions and macromolecules. This lab, identifying organic macromolecules, focuses primarily on the colour changes of the solutions and the molecular changes that lead to these physical changes. Iodine Test Two common polysaccharides, starch and glycogen, serve as energy storage molecules in plants and animals respectively. Starch consists of two major polysaccharides: amylose and amylopectin, both of which are composed of chains of D-glucose units joined by α-1, 4-glycosidic bonds. While amylose has an unbranched helical structure, amylopectin is highly branched with α-1, 6-glycosidic bonds joining the branches at the branch points.

There are four types of biomolecules, carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are large chains of sugar found in food and living tissues. This includes sugars, starch, and cellulose. They have the same ratio of hydrogen and oxygen that water has, 2:1. They are broken down to release energy in the animal body. Lipids are any organic compounds that are fatty acids and don’t dissolve in water but do in organic solvents. Fatty acids can be found in natural oils, waxes, and steroids. Proteins are macromolecules that do everything in the cell. They are tools and machines that make things happen. Nucleic acids are long strands of nucleotides, and function primarily in storage and transmission of genetic information. There are two types of nucleic acids, DNA and RNA. DNA is the genetic material of all cellular organisms, and RNA sends out messages from the information that is held in the DNA.
