1. Consider serine (it is expected you will need to refer to a chart of the 20 common amino acids to find structure information for this and other amino acids). a. Draw its complete Lewis structure of serine (show all atoms, bonds and lone pairs). Draw the version of the structure without any charges b. Identify all of the functional groups C. Draw the Zwitterion form of serine d. Explain how the Zwitterion is formed from the uncharged version 2. Draw the Lewis structure of the dipeptide that results when histidine reacts with valine. escribed by Phe-Trp-Cys. Your drawing can be a Lewis structure,

A. Structural Isomerism of Alkanes, continued. Construct models for the five alkanes that have the molecular formula C6H₁4. All five of your models should have the same number of each type of atom, but they should have the atoms connected in a different order. Thus the molecules they represent are structural isomers of one another. Note the tetrahedral geometry of each carbon atom. Draw an extended and a condensed structure (NOT skeletal/line angle) of each structural isomer, then determine its IUPAC name. Recall that since the IUPAC name specifies the number of each type of atom and how they are connected, each structural isomer will have a different name. Each name should very specifically describe the structure.

Doxorubicin, shown here, is an important chemotherapy drug used to treat avariety of cancers, including bladder cancer, breast cancer, and certain forms of leukemia. Doxorubicin works by binding to DNA in such a way that a portion of it penetrates the DNA double helix— a process called intercalation. During transcription— the process that forms RNA— portions of the DNA strands are temporarily separated for the base sequence to be read and then are reconnected. With bound doxorubicin, however, the double helix does not reform properly after the strands are separated, which disrupts replication— the process that forms an identical copy of DNA. Which portion of doxorubicin do you think intercalates into the DNA double helix, and why do you think it has little difficulty doing so?

Fatty acids are molecules with a carboxylic acid on one end and long hydrocarbon chain on the other. The sodium salts of fatty acids (such as sodium strearate, shown below) are commonly used in soaps to trap nonpolar dirt and grease particles. Soap does not work well in "hard water, which is water with high concentration of magensium and calcium ions (often found in water obtained from wells) Explain this observation at a molecular level.
