tertiary protein structure functional groups

Post by junkeeroo » Tue Jan 12, 2010 9:50 pm

Hi all,

Would appreciate if you could help me with this question that I'm struggling with. Thanks in advance!

Which of the following functional groups forms cross bridges that help stabilize protein tertiary structures?
a. hydroxyl
b. carbonyl
c. amino
d. phosphate
e. sulfhydryl

Cis or trans? That's what matters.

I focused on the word 'stabilize' more than I did the 'cross bridges' and center it all the word tertiary structure (not secondary structure, like in polypeptides).

all of them is the answer as the 4 types of bonding (namely hydrogen, hydrophobic, electrostatic and disulphide) are involved in making the secondary, tertiary and quatenary structure)
it isn't what you do that matters but it is how you do it

all of the 4 bonds stabilise.
and as i stated in my earlier post all 4 are involved in the sec, tert and quat structure :wink:
