On the molecular scale, members of three of these classes—carbohydrates, proteins, and nucleic acids—are huge and are therefore called macromolecules. For example, a protein may consist of thousands of atoms that form a molecular colossus with a mass well over 100,000 daltons. Considering the size and complexity of macromolecules, it is noteworthy that biochemists have determined the detailed structure of so many of them. The image in Figure 5.1 is a molecular model of a protein called alcohol dehydrogenase, which breaks down alcohol in the body.  \nThe architecture of a large biological molecule plays an essential role in its function. Like water and simple organic molecules, large biological molecules exhibit unique emergent properties arising from the orderly arrangement of their atoms. In this chapter, we’ll first consider how macromolecules are built. Then we’ll examine the structure and function of all four classes of large biological molecules: carbohydrates, lipids, proteins, and nucleic acids.  \n The scientist in the foreground is using 3-D glasses to help her visualize the structure of the protein displayed on her screen.  \nGet Ready for This Chapter  \nCONCEPT 5.1  \nMacromolecules are polymers, built from monomers  \nLarge carbohydrates, proteins, and nucleic acids are chainlike molecules called polymers (from the Greek polys, many, and meros, part). A polymer is a long molecule consisting of many similar or identical building blocks linked by covalent bonds, much as a train consists of a chain of cars. The repeating units that serve as the building blocks of a polymer are smaller molecules called monomers (from the Greek monos, single). In addition to forming polymers, some monomers have functions of their own.  \nThe Synthesis and Breakdown of Polymers  \nAlthough each class of polymer is made up of a different type of monomer, the chemical mechanisms by which cells make and break down polymers are basically the same in all cases. In cells, these processes are facilitated by enzymes, specialized macromolecules that speed up chemical reactions. The reaction connecting monomers is a good example of a dehydration reaction, a reaction in which two molecules are covalently bonded to each other with the loss of a water molecule (Figure 5.2a) . When a bond forms between two monomers, each monomer contributes part of the water molecule that is released during the reaction: One monomer provides a hydroxyl group ( ¬ OH), while the other provides a hydrogen ( ¬ H) . This reaction is repeated as monomers are added to the chain one by one, making a polymer (also called polymerization) .  \nPolymers are disassembled to monomers by hydrolysis, a process that is essentially the reverse of the dehydration reaction (Figure 5.2b) . Hydrolysis means water breakage (from the Greek hydro, water, and lysis, break) . The bond between monomers is broken by the addition of a water molecule, with a hydrogen from water attaching to one monomer and the hydroxyl group attachi","cbCaic2YDbC08bLn","https://ap.wps.com/l/cbCaic2YDbC08bLn","pdf",4333363,26,"English","# The Molecules of Life\n## Large molecules as four classes\n# The Architecture of Large Biological Molecules\n## Emergent properties and structure-function\n# Get Ready for This Chapter\n## Concept 5.1 Macromolecules are polymers, built from monomers\n# The Synthesis and Breakdown of Polymers\n## Dehydration reactions and polymerization\n## Hydrolysis and digestion\n# The Diversity of Polymers\n## Limited monomers, vast variety","[{\"question\":\"How does hydrolysis break polymers into monomers?\",\"answer\":\"Hydrolysis reverses dehydration by adding a water molecule to break the bond between monomers.
