Denaturation of Protein by Strong Acid  John W. Moore, Jerrold J. Jacobsen, Gary Trammell, Kristin Johnson
"Strong acid denatures egg white proteins.This video contains voiceover:""The tertiary structure of egg white proteins is held together by hydrogen bonding and hydrophobic interactions. Adding strong acid to the protein disrupts the intermolecular forces, and the tertiary structure is lost. The loss in protein structure is called denaturation. The proteins precipitate, forming a white solid."""

Biochemistry : ComplementaryDNA (20 Variations)
Determine the sequence of the complementary DNA strand for the following sequence. (Note: Complementary strands match up 5' ends to 3' ends.)
5'-TAATGAGT-3'

Nucleic Acids / DNA / RNA
Biochemistry : HBondingDNA (9 Variations)
The structure and replication of DNA are strongly dependent on the hydrogen bonding system present in the double helix. How many functional groups in thymine can participate in hydrogen bonding? (This means all the groups, not just the ones that actually participate in hydrogen bonding in the double helix.)

Molecules and Medicine (E. J. Corey, Barbara Czakó, and László Kürti)  Robert E. Buntrock
Looking for a book on common drugs and pharmaceuticals? On diseases and medical conditions? On pharmacology? In addition, do you need some background in chemistry to handle all of this information? If you want all of this, and in addition want it under one cover, then this is the book for you.

A-DNA and B-DNA: Comparing Their Historical X-ray Fiber Diffraction Images  Amand A. Lucas
This paper provides a comparative explanation of the structural content of the diffraction diagrams of A-DNA and B-DNA that facilitated the discovery of the double-helical structure of DNA by Watson and Crick in 1953. This analysis is supported a method that simulates both A-DNA and B-DNA X-ray images optically.

Kinetic Analysis of Amylase Using Quantitative Benedict's and Iodine Starch Reagents  Beverly Cochran, Deborah Lunday, and Frank Miskevich
This laboratory emphasizes that enzymes mediate the conversion of a substrate into a product and that either the concentration of product or reactant may be used to follow the course of a reaction. It does so by using an inexpensive scanner and open-source image analysis software to quantify amylase activity through the breakdown of starch and the appearance of glucose.

Biomolecules (Netorials)  Rachel Bain, Mithra Biekmohamadi, Liana Lamont, Mike Miller, Rebecca Ottosen, John Todd, and David Shaw
Biomolecules: this is a resource in the collection "Netorials". This set of modules will provide you with a descriptive overview of the four major classes of biomolecules found in all living organisms: carbohydrates, lipids, proteins, and nucleic acids. The Netorials cover selected topics in first-year chemistry including: Chemical Reactions, Stoichiometry, Thermodynamics, Intermolecular Forces, Acids & Bases, Biomolecules, and Electrochemistry.

Molecular Models of DNA  William F. Coleman
The featured molecules this month come from the paper by David T. Crouse on the X-ray determination of the structure of DNA. Given that most students are aware of the double helix, it seems appropriate to back up a little and examine the components that give rise to this structure. Accordingly, the molecule collection includes: Purine and pyrimidine, structural precursors of the four bases found in DNA: cytosine (C), thymine (T), adenine (A), and guanine (G) The four corresponding deoxyribonucleosides The four deoxyribonucleotides (the nucleoside monophosphates) A two-base-pair fragment showing the AT and GC hydrogen-bonded complements Several small 24-base-pair DNA fragments polyAT, polyGC, and a random array of bases. The DNA fragments provide a good opportunity to have students explore features of the Jmol and Chime menus. Using the Jmol menu as an example (right-click on the structure to bring up the menu) students can use the measuring tools to get an idea of the length of a complete turn in the DNA, the relative widths of the major and minor grooves, and the diameter of the helix. They can use the coloring schemes to detect the various base pair combinations, and learn to read the code for the random sequence. In Chime they can use the Shapely coloring scheme for this same purpose. Exploring other aspects of the menu will allow students to present the molecules in the various forms, including ribbon and cartoon views. In RNA, thymine is replaced by uracil, and the sugar moiety has an axial hydroxyl group on the carbon atom adjacent to the base binding site (the 2? carbon). The structures of uracil and of uridine monophosphate are included in the molecule collection. Students can use the Web to download and examine more complex DNAs using a site such as the Nucleic Acid Database at Rutgers University.
