Chapters 4 and 5: Dr. Anita Latham 1) Look at figure 4.5 in chapter 4 and determine which pair(s) of molecules is(are) isomers of each other, identifying the type(s) of isomers. 2) How many molecules of water are needed to completely hydrolyze a polymer that is 10 monomers long? 3) Name the type of bond present in each of the following: proteins, nucleic acids, polysaccharides 4) Why does a denatured protein no longer function normally? 5) Each phosphodiester linkage in DNA or RNA includes a phosphate joined by covalent bonds to a) two bases, b) two sugars, c) two additional phosphates, d) a sugar, a base, and a phosphate, e) a sugar and a base Key: 1) Look at figure 4.5 in chapter 4 and determine which pair(s) of molecules is(are) isomers of each other, identifying the type(s) of isomers. Butanes in b are structural isomers as are butenes in c.

Unformatted text preview: 2) How many molecules of water are needed to completely hydrolyze a polymer that is 10 monomers long? Nine, with one water required to hydrolyze each connected pair of monomers. 3) Name the type of bond present in each of the following: proteins, nucleic acids, polysaccharides Proteins: peptide bond, nucleic acid: phosphodiester bond, polysaccharides: glycosidic bond 4) Why does a denatured protein no longer function normally? Function of a protein is a consequence of its structure. On denaturation the structure is lost hence the protein is no longer able to function normally. 5) Each phosphodiester linkage in DNA or RNA includes a phosphate joined by covalent bonds to a) two bases, b) two sugars, c) two additional phosphates, d) a sugar, a base, and a phosphate, e) a sugar and a base b)...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
