What are polymers? For one thing, they are complex and giant molecules and are different from low molecular weight compounds like, say, common salt. To contrast the difference, the molecular weight of common salt is only 58.5, while that of a polymer can be as high as several hundred thous...
Polymers are high molecular mass (103−107u) substances consisting of a very large number of simple repeating structural units joined together through covalent bonds in a linear fashion. Polymers are also called macromolecules. Some examples of polymers are : polythene, nylon 6,6 backlite, rubber...
What are polymers?Biological Molecules:Many biologically important molecules consist of chains of many smaller molecules linked together. For instance, nucleic acids are long chains of nucleotides, carbohydrates are long chains of sugar molecules, and proteins are long chains of amino acids....
Step-by-Step Solution:Step 1: Define Polymers - Polymers are large molecules that are made up of repeating structural units called monomers. These monomers are smaller, simpler molecules that bond together in a
What are glucose polymers called? Organic Chemistry - Glucose Polysaccharides Polymers are formed when several single units of molecules (referred to as monomers) are joined together by a chemical bond. In the case of glucose, a simple sugar monomer, or what we can specifically call a monosacchar...

Polymers (“poly” = many; “mer” = unit) are long-chain molecules that consist of “many units”, i.e., repeating sections of monomers --- like links in a chain --- e.g., polyethylene would consist of many ethylene (-CH2-CH2-) units. These monomers can be added one to another...
Lipids create a unique type of polymer, known for being a key component of cell membranes and hormones. Where most polymers are long chains of identical, repeating carbon-containing molecules known as monomers, lipid polymers contain an additional, nonid
Other varieties of natural polymers are available (e.g., cellulose is themain constituent of wood and paper).1.1 MicrostructureThe microstructure of a polymer (sometimes called‘configuration’) relates to thephysical arrangement of monomer residues along the backbone of the polymer chain.These are ...
Everyday items including milk jug, grocery bags, and takeout containers are made from a class of polymers called polyolefins. These plastics are really durable(耐用的) because the chemical bonds in those polymers are extremely stable. In a world set up for disposable (一次性的) items, ...
