form larger molecules known as polymers. In doing so‚ monomers release water molecules as byproducts. This type of reaction is known as dehydration synthesis. In a dehydration synthesis reaction‚ the hydrogen of one monomer combines with the hydroxyl group of another monomer‚ releasing a molecule of water. At the same time‚ the monomers share electrons and form covalent bonds. As additional monomers join‚ this chain of repeating monomers forms a polymer. Polymers are broken down into monomers in

Clinton would later be acquitted in February. In March‚ the Supreme Court upheld the murder convictions of Timothy McVeigh for the Oklahoma City bombing. The case would become important because it expanded the ruling of a police stop and frisk. This means that the case set a new precedent. The

#4 The Synthesis of Organic Polymers CHM2123‚ Section C October 21‚ 2014 Introduction: Organic polymers are macromolecules that are composed of smaller molecules called monomers. There are two main groups of polymers: natural polymers and unnatural (synthetic) polymers. Natural polymers include proteins such as cellulose and starch and are a necessity for our existence. On the other hand‚ synthetic polymers such as the polycarbonate in our lab goggles are

A protein is a Biological polymer made up of as different amino acids joined by peptide bonds. A protein is formed by amino acids which are the basic building block of a protein components of an amino acid include a :C-carbon atom‚ H-Hydrogen atom‚ H3N+ - Amino Group‚ COOH- - Carboxyl Group‚ R- this group varies from amino acid to amino acid. There are 20 amino acids‚ each differing in its R group. Two examples are: Glycine‚ its R group being H(Hydrogen) and Phenylalanine its R group being CH2 (Carbon

Effect of Temperature on Polymers: Solids on heating eventually melt to form a liquid. With polymers it is not so simple rubber on cooling (in liquid nitrogen) becomes brittle or glassy. Many polymers have a mixture of ordered (crystalline) regions and random (amorphous) regions. In the glassy state‚ the tangled chains in the amorphous region are frozen so movement of chains is not possible the polymer is brittle. If the glassy material is heated‚ the chains reach a temperature at which they

Once natural wax‚ protein‚ and other unnecessary things are removed‚ what’s left is a natural polymer of pure cellulose. Cellulose is the structural component of the cell walls of green plants‚ many forms of algae and the oomycetes. Some species of bacteria separate it to form biofilms. Cellulose is the most common organic compound on Earth. About
