didn't you already have to do that for biology?juniper456 said:do we have to? i.e., which ones are hydrophobic, hydrophilic, acidic, basic, etc. . .
"His goes both ways. . ." heee heeeeeUCLAstudent said:Yes, it's glycine. Juniper, you definitely don't need to know the structures of all of the side chains. It can't hurt to be able to categorize the different amino acids. By categorize, I don't mean that you have to be able to recite which amino acids are polar uncharged or hydrophobic, but I would be familiar enough to distinguish which amino acid is the "odd one," given four answer choices. And, be sure to know the biological implications of histidine due to its near-physiological pka. Hope this helps!
UCLAstudent said:I do have lots of mnemonics, but they were mostly for memorizing the one-letter designations for the amino acids (which you do not need to know).
W = tryptophan = tWo rings
Q = glutamine = Qtamine ("cute-amine")
R = arginine = Arrrrrrrrrginine
V = valine (side chain is shaped like a V)
F = phenylalanine = Fenylalanine
As you can see, these won't be terribly useful for the MCAT. I will get back to you if I remember something more useful.
i read about them in my princeton review book. . .stoleyerscrubz said:Anything else to know beyond what EK goes over on amino acids? Ek devotes one paragraph to this and just classifies them by basic,acid,polar, and nonpolar.
Juniper, how did you know which was achrial and about Histidine? I don't remember Prof Alaie going over that. I must've been busy writing notes 100mph.
you don't have to memorize structures. in fact, you really shouldn't waste your time memorizing when you could be using that time to do something mroe important. however, you should know a few key ones... i'm sure it tells you this in whatever book you're working with. also you should know trivia (i.e. glycine is achiral), and general classifications... acidic, basic, etc.juniper456 said:do we have to? i.e., which ones are hydrophobic, hydrophilic, acidic, basic, etc. . .
