Chapter 31, Problem 31.29P
An isoprene unit can be thought of as having a head and a tail. The “head” of the isoprene unit is located at the end of the chain nearest the branch point, and the “tail” is located at the end of the carbon chain farthest from the branch point. Most isoprene units are connected together in a “head-to-tail” fashion, as illustrated. For both lycopene (Problem 31.26), and squalene (Figure 31.9), decide which isoprene units are connected in a head-to-tail fashion and which are not.
These two isoprene units are
connected in head-tail fashion.

Because of the addition of water, the mass of the glucose monomer increases during hydrolysis from approximately 162g/mol in the starch polymer to 180g/mol as free sugar. The glucose, in turn is converted to ethanol by the yeast, Saccharomyces cerevisiae, according to the reaction, C6H12O6 -> 2 CO2 + 2 C2H5OH. The starch in 25kg (~1 bushel) of corn is hydrolyzed and in the process 1.8kg of water (H2O) is consumed. How many moles of glucose (C6H12O6) would you expect to be produced?

- Monosaccharides are cyclic hemiacetals that can react with alcohols to form acetals. The bond between the anomeric carbon atom of the monosaccharide and the oxygen atom of the -OR group is called a glycosidic bond. The name of the linkage contains the designation alpha (a) or beta (B) (from the anomeric carbon in the glycosidic bond) and the carbon numbers for the carbons from the two sugars. For this example, the linkage is an a-1,4 glycosidic bond. Н НО HO اب تاب است H OH H OH -OH Н Н OH H + OH HO a anomer CH₂OH H Н H О OH H2C OH Н H Classify the glycosidic linkage in the disaccharide.
