    what the heck? are you sure that you are taking orgo? not biochem or bioligocalorganicchemistry?

    is it just me or do you guys think these questions are kinda hard? in fact, i only haven't learned IR and NMR in the entire serie of ochem in my school, yet i don't even know all of these answer! have i learned them before???

    arh~~

    i meant, of course i leanred stereochem and d and l those things, but i never applied them to biochem molecule. unless the structure of the molecule is provided, it's very hardsh of him to ask you question like that.

    :rolleyes:

    maybe that i am just dumb.

    Hey, you can't answer those questions online in a post. You're asking for structural stuff, that needs to be drawn out.

    Besides, that sounds like the whole of my second or third second semester orgo test from sophomore year. And who wants to remember that!

    Yeah, GW uses Wade too. I mean, I don't know if they're still using it. It wasn't that bad.

    1) It's kind of hard to see, but over the picture is the structure of cortisone

    http://inventors.about.com/gi/dynamic/offsite.htm?site=http://web.mit.edu/invent/www/inventorsI%2DQ/julian.html

    2) About halfway down (right before disaccharides) is the alpha chair form. You should be able to figure out the beta if you need both.

    http://www.indstate.edu/thcme/mwking/carbohydrates.html

    3) About halfway down the pages, there's a fischer projection of serine.

    http://www.biocheminfo.org/klotho/html/D-serine.html
    http://www.biocheminfo.org/klotho/html/L-serine.html

    Another version:

    http://chemistry.about.com/library/weekly/blaminochiral.htm


    I'd look for more, but I've got to go now. Hopefully these will be some help.
