MW polymer is that the solvent added (solution process) has made the monomer concentration much lower than the bulk process. In solution process‚ only soluble and low molecular weight polymers could be obtained because of chain transfer reactions with the solvents. The solvent in the solution process act as good heat conductor but also significantly lowered the monomer concentration. In contrast‚ bulk process enables high monomer concentration without addition of solvent. As a result‚ high MW polymers

The Molecules of Cells (Chapter 3 in your textbook) Without water and carbon-based molecules‚ no life as we know it! Carbon: The Backbone of Life • Living organisms consist mostly of carbon-based compounds Also‚ H‚ N‚ O‚ P‚ and S…… • Carbon is unparalleled in its ability to form large‚ complex‚ and diverse molecules. Why? Principal source of carbon on Earth? • Proteins‚ DNA‚ carbohydrates‚ lipids‚ and other molecules that distinguish living matter are all composed of carbon. C21H36N7O16P3S Coenzyme

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 chapters on metabolism‚ molecular biology‚

Mastering Concepts 2.1 1. Which chemical elements do organisms require in large amounts? Carbon‚ oxygen‚ hydrogen‚ nitrogen‚ sulfur‚ and phosphorus are the chemical elements that organisms require in large amounts. 2. Where in an atom are protons‚ neutrons‚ and electrons located? An atom’s protons and neutrons are in its nucleus. A cloud of electrons surrounds the nucleus. 3. What does an element’s atomic number indicate? An atom’s atomic number indicates the number of protons in its nucleus

Acid. • Proteins - monomers are amino acids and proteins are used for various reasons in cell such as structure‚ defense‚ modification. An example of a protein is hemoglobin that red blood cells used to carry oxygen. • Carbohydrates - monomers are monosaccarides with the general formula of CH20. Carbohydrates can be used for storage or energy or even for structure‚ such as the cellulose that makes up the plant cell wall. • Nucleic Acids - RNA and DNA‚ the monomers of both of them are nucleotides

this experiment we will be testing what would happen to the polymer when we add borax to it. A polymer is a compound made up of large molecules often in a solid state. Polymers are chemically formed by 100 to 10‚000 small molecules called "monomers". Monomers occur in molecular units or patterns that look like beads on a string. Polymers are also formed by large atoms. They form into long and flexible chains. Polymers are found in plastics‚ fibreglass‚ and many more product manufacturer. Polymers
