When cellulose is synthesized, each time a new monomer is added, a molecule of water is released. This occurs through a condensation reaction where a hydroxyl group (\u2013OH) from one glucose molecule reacts with a hydrogen atom (\u2013H) from the other monomer, forming a glycosidic bond and releasing one molecule of water.<\/p>\n\n\n\n<p>To understand how many water molecules are released in the polymerization of a cellulose molecule that is 20 monomers long, let&#8217;s break it down:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>For the first monomer, there is no water released, as it is the starting point of the chain.<\/li>\n\n\n\n<li>For each additional monomer added, a water molecule is released.<\/li>\n\n\n\n<li>If the molecule has 20 monomers, then 19 bonds are formed between the monomers (one less than the total number of monomers because the first monomer does not require a bond).<\/li>\n<\/ul>\n\n\n\n<p>Thus, <strong>19 water molecules<\/strong> are released as 19 glycosidic bonds are formed between the 20 glucose units.<\/p>\n\n\n\n<p>This concept of water release due to condensation reactions is common in the formation of polysaccharides like cellulose and starch, where each addition of a monomer to the polymer chain involves the release of one water molecule.
