A different set of notes for sunday's review...

Sunday Review 10/16
(I am going to make this short, because I am a little on the tired side so I hope this helps.)
• Know amino acids: mainly L, know the structure and how they look, fisher projections, R is coming at you H is in the board, H matters where amino acids are located, understand importance of the R group position.
• Know the how to use acid base chemistry. pH=pKa + a/ha, understand titration curves and how to read them
• Understand bonds in the peptide
• Know 1 2 3 4 structure characteristics, the importance of H bonding, alpha helixes, beta sheets
• Hemoglobin! Inactive is T state, active is R state. Binds to O2, CO2, CO and BPG, understand fig. 5-10, fig 5-16 and fig 5-17
• Sugars, know how to change conformations, know how to make rings, (If it was LEFT UP to me, I would be DOWN RIGHT pissed that I had to learn this) remember this for positions of OH when going from chain to ring. If you look at the two points sticking of the ring (like 1 and 4) if they are in trans than it is beta, if they are cis than it is alpha. Know how linkage happens, pg 246, fig 7.16a.
• For nucleotides, know what he covered very well because it was very little, nucleotides are base, P and sugar; nucleosides is just base and sugar, know bases and basic structure and chemistry, fig 8.8, know Avery and the mouse experiment, know Hershey and Case and radioactive experiment, figure 8-33 thru 36
* I know this is short, I hope it helpful is some why. GOOD LUCK!!
