my biochem prof is a total idiot. i am looking over the practice quiz and there are all these questions about alpha and beta carbons and he hasn't even told us what those are. i have googled it and looked in the book and it says the carbon next to the functional group. only problem with that is that all amino acids have an amine group and a carbonyl group...which group am i supposed to look at? i'm so lost

Criminy it has been thirty plus years since I had analytical chemistry. If you had asked me this question thirty years ago I would have a better answer but today all I can say is, did you look at wikipedia?
http://en.wikipedia.org/wiki/Alpha_and_beta_carbon

haha i just hate wikipedia. and i did look but they don't give an example of an amino acid in a drawing. the wording just confuses the crap out of me. the example they give is just an organic molecule with a phenyl group and a carbonyl which doesn't really pertain to what i'm looking at. i would ask my prof but he is a total doofus. thanks though.

How 'bout this?
 I got my chemistry books out but I couldn't find much. Plus the books are from 1974 FWIW. Oh well. Yoda tried to help.

So in that case the middle carbon attached to the amino group is the alpha and the carbon in the R group would be the beta? I asked my friend who is in my class and she couldn't really explain it either so tomorrow during his office hours we're going to go in with some questions. thanks though lol
