mutarotation

Mutarotation is when the optical rotation of a compound changes over time. This happens with freshly made solutions. Take D-glucose for example. When freshly dissolved in water, the solution is made up of alpha-D anomer only (ring structure). Then it slowly reverts to the open chain conformation, and back into the ring, a portion of which will form the beta-D anomer. It eventually reaches an equilibrium where all configurational species exist . That's why the configuration of the anomeric carbon (the carbon that determines the alpha- and beta-ness) of solutions in equilibirum is unknown.

Damn! I hate conformation, configuation, nomenclature and such.

I got my official GRE scores today.

Verbal: 580 (79%)
Quantitative: 750 (79%)
Analytical Writing: 4.0 (32%)

I'm definitely disappointed with my Analytical writing score. The score description for scores between 4 and 3.5 read:
Provides competent analysis of complex ideas; develops and supports main points with relevant reasons and/or examples; is adequately organized; conveys meaning with reasonable clarity; demonstrates satisfactory control of sentence structure and language usage but may have some errors that affect clarity.
"competent...adequately....reasonable...satisfactory" Okey, so it's not TOO bad. And I did predict my score to be 4, which is the average of (4 or 5) and (3 or 4). Still, I was hoping to get a higher score.

And what the hell do those percentile rankings mean? How can I be 750 over 800 in the Quant and still be 79%? I demand an explanation ... or a recount!

Damn!

i think it's because a lot of people do well in quantitative. like it's usual to get near 800s and that is why your percentile ranking is low.

also hate conformational stuff. *sigh* especially the moving electrons.
