Alpha helix - Study guides, Class notes & Summaries

The right-handed alpha helix - Answer - An example of secondary structure; the alpha helix found in proteins is RIGHT-HANDED; spirals upwards in the counterclockwise direction About the alpha helix - Answer - AA side chains and H atoms on each alpha carbon project out from the axis; no noticeable hole in the middle because of atomic radii - intramolecular H bonds connect the carbonyl C of one aa residue to the peptide H in the 4th residue - H-bond are nearly parallel to the axis of the hel...

What is the basic structure of an amino acid? What do they look like? - amino group (NH2 or NH3), carboxyl group (COO or COOH), alpha carbon (C), and variable group How do you identify the 3 different types of side chains: non-polar/hydrophobic, polar, and charged? - Non-polar/hydrophobic - end with CH or "can't have" water. Polar - end with OH, SH, or NH. Charged - end with a charge what kinds of bonds do each of the 3 different types of side chains make? - ionic, hydrophobic/nonpolar, ...

AP Biology - The Chemistry of Life Latest Update Already Passed 4 classes of organic molecules 1. carbohydrates 2. proteins 3. lipids 4. nucleic acids acid substance that increases the molarity of hydrogen ions in a solution, decreasing pH (simultaneously diminishes the molarity of hydroxide ions, because product of the molarities of both is always 10^-14) adhesion the tendency of water molecules to stick to other substances; enables transportation of H2O against gravity in vascular...
