Yvan Mamboukuate 10/09/2013 BIO 101 Lab Report Biological Molecules Introduction: In this experiment‚ simple chemical tests will be performed to identify the presence of various types of biological molecules. These tests take advantage of the fact that different types of molecules have different functional groups and‚ therefor‚ different chemical properties. Thus‚ they will react to test reagents (also called indicators) differently. Materials: Biuret‚ Sudan III‚ Iodine‚ Benedict‚ water

Biological Molecules Lab Report EXERCISES 1 & 2 QUALITATIVE TESTING FOR BIOLOGICAL MOLECULES 1) Complete the table for your group ’s samples. Be sure to clearly indicate in the blue line whether or not your sample was positive (+) or negative (-) for the given test. Then below that in the white area‚ type your observations‚ mainly focusing on the color‚ but also the layering as appropriate. Be sure your interpretations match your observations! The chart area will expand as you type. BENEDICT ’S

What happens to protein when they are exposed to very high temperatures? Proteins exposed to very high temperatures become denatured. Meaning they change shape. If a protein is denatured

There are four biological marcomolecules essential to the function of a cell: lipids‚ proteins‚ carbohydrates and nucleic acids. Proteins are made up of amino acids that have a carbon in the center of the structure with four chemical groups attached to the sides. Traditionally protein is understood to assist in the development of muscle in athletic people‚ but it actually functions as structural support‚ cell adhesion‚ transport for molecules‚ and cellular communication. Through dehydration synthesis

Bio-Rad Protein Assay INTRODUCTION Proteins are large complex organic macromolecules which are utilized for many important roles in the body. Proteins function in structure‚ transport‚ energy conversions‚ and play an important role in defense against diseases. Protein is also important for muscle recovery‚ which is why it is commonly associated with fitness. Though your body will always absorb 1g of protein the same way every time‚ protein companies like to make their product competitive

AS Biology‚ Biological Molecules Revision Notes Distinguish between monomers and polymers: Monomers- Identical small molecules. Polymers- Chainlike molecules formed from the linking together of many similar. Distinguish between monosaccharides‚ disaccharides‚ and polysaccharides: Monosaccharides- Simple sugars; sugar molecules may be enantiomers due due to the spatial arrangement of parts around asymmetric carbons; raw material for synthesis of other organic molecules. Disaccharides-

Campbell’s Biology‚ 9e (Reece et al.) Chapter 5 The Structure and Function of Large Biological Molecules In Chapter 5‚ the principles of chemistry covered in earlier chapters are applied to the understanding of biological polymers and lipid membranes. The emphasis is on properly linking monomers and their polymers‚ and on the structural and functional diversity of the different polymer types. Particular attention is given to protein structure‚ because this is central to understanding subsequent

Detection of Biological Molecules Introduction: Without carbon‚ nitrogen‚ hydrogen‚ sulfur‚ oxygen and phosphorus‚ life wouldn’t exist. These are the most abundant elements in living organisms. These elements are held together by covalent bonds‚ ionic bonds‚ hydrogen bonds‚ and disulfide bonds. Covalent bonds are especially strong‚ thus‚ are present in monomers‚ the building blocks of life. These monomers combine to make polymers‚ which is a long chain of monomers strung together. Biological molecules

that diatomic molecules make up majority of the Earth’s atmosphere? The prefix “di” means ‘’two’’ in Greek‚ so these diatomic molecules are made up of two atoms. In this lesson‚ we will discuss diatomic molecules and go over some examples. !!!What is a Diatomic Molecule? Diatomic molecules are all around us. The Earth’s atmosphere is mainly composed of about 78% oxygen and 21% nitrogen. The oxygen and nitrogen present in the atmosphere are both in the form of ‘’diatomic molecules’’‚ as shown below:
