Monomer and polymer definationwith example |
| Answer» <html><body><p><em><strong>Answer:</strong></em></p><p><em><u><strong>Monomers</strong></u></em></p><p><em><strong>The word monomer comes from mono- (one) and -mer (part). Monomers are small molecules which may be joined together in a repeating fashion to form more complex molecules called polymers. Monomers form polymers by forming chemical bonds or binding supramolecularly through a process called polymerization.</strong></em></p><p><em><strong>Sometimes polymers are made from bound groups of monomer subunits (up to a few dozen monomers) called oligomers. To qualify as an oligomer, the properties of the molecule need to change significantly if one or a few subunits are added or removed. Examples of oligomers include collagen and liquid paraffin.</strong></em></p><p><em><strong>A related term is "monomeric protein," which is a protein that bonds to make a multiprotein complex. Monomers are not just building blocks of polymers, but are important molecules in their own right, which do not necessarily form polymers unless the conditions are right.</strong></em></p><h3><em><u><strong>Examples of Monomers</strong></u></em></h3><p><em><strong>Examples of monomers include vinyl chloride (which polymerizes into polyvinyl chloride or PVC), glucose (which polymerizes into <a href="https://interviewquestions.tuteehub.com/tag/starch-1224650" style="font-weight:bold;" target="_blank" title="Click to know more about STARCH">STARCH</a>, cellulose, laminarin, and glucans), and amino acids (which polymerize into <a href="https://interviewquestions.tuteehub.com/tag/peptides-1150255" style="font-weight:bold;" target="_blank" title="Click to know more about PEPTIDES">PEPTIDES</a>, polypeptides, and proteins). Glucose is the most abundant natural monomer, which polymerizes by forming <a href="https://interviewquestions.tuteehub.com/tag/glycosidic-1008626" style="font-weight:bold;" target="_blank" title="Click to know more about GLYCOSIDIC">GLYCOSIDIC</a> bonds.</strong></em></p><p><em><strong></strong></em></p><h3><em><u><strong>Polymers</strong></u></em></h3><p><em><strong>The word polymer comes from <a href="https://interviewquestions.tuteehub.com/tag/poly-2938601" style="font-weight:bold;" target="_blank" title="Click to know more about POLY">POLY</a>- (many) and -mer (part). A polymer may be a natural or synthetic macromolecule comprised of repeating units of a <a href="https://interviewquestions.tuteehub.com/tag/smaller-1213327" style="font-weight:bold;" target="_blank" title="Click to know more about SMALLER">SMALLER</a> molecule (monomers). While many people use the term 'polymer' and 'plastic' interchangeably, polymers are a much larger class of molecules which includes plastics, plus many other materials, such as cellulose, amber, and natural rubber.</strong></em></p><p><em><strong>Lower molecular weight compounds may be distinguished by the number of monomeric subunits they contain. The terms dimer, trimer, tetramer, pentamer, hexamer, heptamer, octamer, nonamer, decamer, dodecamer, eicosamer reflects molecules containing 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and 20 monomer units.</strong></em></p><p><em><strong></strong></em></p><h3><em><u><strong></strong></u></em></h3><h3><em><u><strong>Examples of Polymers</strong></u></em></h3><p><em><strong>Examples of polymers include plastics such as polyethylene, silicones such as silly putty, biopolymers such as cellulose and DNA, natural polymers such as rubber and shellac, and many other important macromolecules.</strong></em></p><p><em><strong></strong></em></p><h2><em><u><strong></strong></u></em></h2><h2><strong><em><u>I HOPE IT HELPS YOU PLEASE MARK THIS AS BRAINLIEST ANSWER AND DO FOLLOW ME</u></em></strong></h2></body></html> | |
