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~~

 

[gooloogooloo]

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.



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!

 

[opus03]

Seems a little overboard to me too....I don't remember some of that junk from 2 semesters of O-Chem or my biochem course!!

 

[gooloogooloo]

maybe consult a biochem text book?

kaos, wow, i guess i am the only person who doesn't remember that i even learned them before...

 

[gooloogooloo]

where are your undergrad?
all of u

 

[kaos]

I guess it's cuz i'm a chem major.

 

[Angeliqua]

Books to try:

Organic Chemistry
Author: Francis Carey (I loved this book, very helpful for MCAT review, too)!

Any Biochemistry book

Good Luck!

 

[gooloogooloo]

kaos, that must be why, i am a double hospitality management and hotel management major after all.













just kidding

 

[gooloogooloo]

angeliqua, hey i used that book in UVa too! cuz it's written by a UVa prof.! now my school started using that book too... but too bad i already missed that phase. instead my phase in my present school uses stupid Wade... does anyone know about that book? WADE? sounds very lame itself...

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

I took those classes at St. Louis University...we also used the Carey Orgo book but I also had one by Hornback that I really like.

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

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.

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