PART 3: 2,3-BUTANEDIOL CH-CH(OH)-CH(OH)-CH, mirror images, not superimposable Build as many models of 2,3-butanediol as you can. First, attach two carbons with a single bond. To each carbon add one carbon, one hydrogen, and one oxygen. To complete the structure, Ti the remaining hydrogen atoms. Remember, a model is not different if it is completely superimposable on one already constructed! 13. How many stereochemically different models are possible for 2,3-butanediol? 14. What characteristic does one of these...

B) disrupts the secondary. tertiary or quaternary structure of a protein. C) is always irreversible. D) hydrolyzes peptide bonds. 40. The carbonyl group consists of A) a carbon-Oxygen-hydrogen structure. B) a carbon-Oxygen single bond. c) a carbon-Oxygen double bond. D) a carbon-oxygen triple bond. 41. The addition of hydrogen to an organic compound or the loss of oxygen is called...

rojection Formulas for each model in #16 (again orient the carbon chain up and down). Are the mirror images "superimposable?" Interchange any two of the groups located at one of the chiral centers on one of the models in # 1 6. What is the stereochemical relationship of the resulting structure with the one that used to be its mirror image? Will this 'new' model be "optically active?" Why or why not? 18.

Which of the following is an acceptable term/name used for a molecule in which two carbons of glycerol are attached to fatty acid chains, and the third carbon of glycerol is attached to a phosphate group? C sphingomyelin C phospholipid C phosphosteroid C triacylglycerol A nucleotide is different from a nucleoside because a nucleotide has C a ribose sugar. C a deoxyribose sugar. C at least one phosphate group. nitrogen-containing base. Most types of molecules in the cell have asymmetric...

A. Enantiomers: Certain substances have the unique property of rotating the plane of plane-polarized light. Such light rotation is detectable with the aid of a polarimeter. In order for a molecule to be optically active it must be chiral. Chiral objects lack a plane of symmetry and are non-superimposable on their mirror images. A sp?- hybridized carbon atom can fulfill these requirements if all four of its substituents are different. 1. Methane a) Prepare a methane molecule and then substitute...

3. Cyclic compounds The presence of the ring in all but very large ring cyclic molecules prevents full rotation of the ring atoms. For this reason, stereoisomerism may also occur in cyclic molecules. a) Prepare a model of cyclohexane, C6H12. Draw the condensed formula. b) Build a model of methylcyclohexane (C7H14) by replacing one of the hydrogens of cyclohexane with a methyl group. Draw the skeletal formula for methylcyclohexane. 2 c) How many different isomers exist for methylcyclohexane (CyH34)? d)...

Week 10- Constitutional isomers Constitutional isomers have the same molecular formula, but their atoms are bonded in different orders. These may be further distinguished as chain isomers, which differ only in hydrocarbon chain structure, positional isomers, which differ in the location of a functional group, and functional group isomers which differ in the nature of their functional groups. Typically chain and position isomers show only modest differences in their physical and chemical properties, while functional group isomers differ greatly from...
