A macromolecule can best be described as an immense molecule‚ made up of thousands of covalently bonded carbon atoms. There are four classifications of macromolecules: carbohydrates‚ lipids‚ proteins‚ and nucleic acids. Each classification performs specific functions that allow cells to grow and survive. Macromolecules can be either split or bonded through dehydration synthesis or hydrolysis. Dehydration synthesis occurs when water is released‚ electrons become shared‚ covalently bonding two

The Different Roles of Macromolecules in Biology.There are four types of macromolecules that I am going to describe: Proteins‚ carbohydrates‚ lipids and nucleic acid. I will also describe the functions and why they are important in our bodies. Proteins Proteins are polymers of amino acids that are joined head-to-tail in a long chain that is then folded into a three-dimensional structure unique to each type of protein. The covalent linkage between two adjacent amino acids in a protein (or polypeptide)

PURPOSEThe purpose of the lab is to learn how to determine the presence of glucose‚ starch‚ lipid‚ and protein in various samples through standard tests. MODIFICATION1. Protein solution‚ vegetable oil‚ glucose solution‚ sucrose solution‚ starch solution and distilled water were added separately into six marked test tubes. The volume added was about one finger thick in depth of a test tube. 2. 5 drops of Iodine solution was added to each test tube. 3. The sample’s reaction with iodine was recorded

In the sandwich you just ate‚ you have consumed three raw macromolecules. The bread would be considered the carbohydrate. The mayonnaise is the lipid. The turkey is of course considered the protein. Although the body takes in these three different forms one way‚ the way the body breaks it down is in three ways. First is the break-down of the carbohydrates(bread). The polysaccharide form of this is too big for the body to simply break down directly. So‚ instead the body uses multiple forms of procedures

the subunits help to stabilize the overall structure. For example‚ insulin (a globular protein) has a combination of hydrogen bonds and disulfide bonds that cause it to be mostly clumped into a ball shape. Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. Dna And

MACROMOLECULS LAB: What are the mystery powders? Period: 4 Asia Enoch Introduction: A carbohydrate is an immediate form of energy in your body. Monomers is smaller than a polymer. For carbohydrate the monomer is sugar and the polymer is a polysaccharides. Carbohydrates are important to our body because we need to use energy. The purpose of this lab is to figure which one is the monomer and which one is the polymer. Hypothesis: If I place two drops of iodine into the mystery powder‚ it
