The word polymer comes from the Greek prefix poly-, which means "many," and the suffix -mer, which means "parts. Macromolecules typically have more than 100 component atoms. The first man-made plastic was nitrocellulose. Isomer – A monomer or chemical compound that has the same chemical formulaas other monomers or chemical compounds, but a different number of electrons. CODES (3 days ago) What Is A Promoter In Biology Quizlet Cells. Polymer Definition and Examples - ThoughtCo. While thermoset plastics form irreversible chemical bonds when cured, the bonding in thermoplastics weakens with temperature. These links may take the form of covalent bonds or ionic bonds and the polymers can be either synthetic polymers or natural polymers (such as proteins). and career path that can help you find the school that's right for you. All plants and trees are made of polymers, and we utilize them to make everyday items. For instance, wood from trees makes for sturdy furniture (and is even used to make paper). The process by which DNA is copied to RNA is called transcription, and that by which RNA is used to produce proteins is called translation.. DNA replication. Because the molecules consist of many monomers, polymers tend to have high molecular masses. Earn Transferable Credit & Get your Degree. If you looked at paper under a very powerful microscope, you would see that it's made up of smaller molecules arranged in a repeated pattern. A polymer is a large molecule made up of chains or rings of linked repeating subunits, which are called monomers. Plant cell walls are three-layered structures with a middle lamella, primary cell wall and secondary cell wall.The middle lamella is the outermost layer and helps with cell-to-cell junctions while holding adjacent cells together (in other words, it sits between and holds together the cell walls of two cells; this is why it's called the middle lamella, even though it is the outermost layer). See more. Carbohydrates, lipids, proteins, and nucleic acids are all examples of polymers which is why polymers are a key component of human composition. This is one of over 2,200 courses on OCW. German chemist Friedrich Ludersdorf (1801–1886) and American inventor Nathaniel Hayward (1808–1865) independently found adding sulfur to natural rubber helped keep it from becoming sticky.
