hi, I just read biochem book and it says tertiary protein is three dimentional protein.

but shouldn't 2ndary protein also be 3D?

for example, alpha helix should look 3D cuz we can't just say X and Y axis exist. It goes back and forth (close to you vs. alway from you)

Secondary: 3D structure of segment
Tertiary: 3D arrangement of entire polypeptide.

Hahaha, I was thinking the same thing yesterday. I was going to ask my prof...I agree that it is 3D.
But when you think about it, isn't primary also 3D in its own way. I know it is a straight line, but all these R groups popping out from different sides.

That is true. so I guess Svart Aske can add that too?
btw, doc, r u taking biochem too?

I think the point of the structure system is not so much what is 2D and what is 3D, but what section/aspect of the whole is being described. Primary, secondary, tertiary, quaternary structures add up to an understanding of the entire protein.

Biochem indeed. I like this class. Brings O-chem in with some good bio concepts.

Ya, I see what your saying. We need to look at the overall "picture."

thanks. I was wondering too.
