In class on 9/23/10, we finished the organic notes that we started yesterday. Yesterday we stopped on mono/disaccharides, and we started from polysaccharides and into the proteins notes up to acids. Otherwise, there wasn't much else done in class. And, of course, we had homework, which was only the mini assignment that is due on Tuesday and preview and put hypotheses for each statement for UP pgs. 11-18, due tomorrow.

The following are the answers for each blank in the notes, from top to bottom in each box in the notes. The statements in parentheses indicates that there were extra statements provided by Mrs. Andrews: Starting with the last blank in the polysaccharides box: hydrophilic (water is hydrophilic, this statement was stared). Lipids box: hydrophobic, triglyceride, hydrocarbon, dehydrations. In steroids box: left mini box; lipids, hydrophobic, right mini box; anabolic steroids. Hazards of steroid use: east german, testostorone, organ damages, birth defects. Effects on teens: left column; pimples, breasts, tumors, violent, shorter, right column; hormones, development, gender mix-ups. Proteins box: specific sequence of amino acids (20 amino acids, like alphabet), hydrogen (weak), 2 or more (no more than 4) (peptide- bonds between amino acids, covalent bonds- strong bonds, hydrogen bonds- weak). Nucleic acids box: nucleic acids, DNA, RNA. (Next section) PROTEINS= Enzymes. Proteins box: proteins, amino acids. Amino acids box: 20 (stared), carboxl, amino (Remember: most proteins are hydrophilic). Forming Polymers: Dehydration synthesis, peptide (both stared). What is an enzyme?: enzyme, catalysts (Recycled), metabolism, activitation energy (stared). How to speed up a chemical reaction?: heating (a little bit), decrease. Enzymes are affected by...: temperature, pH, concentrations of enzymes or substance, specificity (example under it: 100 enzymes= 100 substrates). pH scale box: 0, 14. Ions box: charged particle, electron, dissociate).
