-- protein structure (https://www.jusunlee.com/forums/showthread.php?threadid=6825)
protein structure
could someone please explain to me how the primary, secondary, tertiary, and quaternary structure of proteins work? n how 4 polypeptide chains n a heme group make up the 3d shape of hemoglobin by these structures? cuz i failed my bio test since i forgot it, n couldnt explain well.....

we juss finished learning the primary, secondary, tertiary, and quarternary consumers of a food chain... buh I bet that is totally different from what you're talking about so I can't help... sorrie... and all this stuff that I'm learning in enviromental biology is so boring... it's stuff that I learned last year... I sleep in the class all the time :sleepy: and I'm still getting a good grade

umm....could u be more specific....what is the R group in this case? the heme? n how does the folding/twisting/watever contribute to the final shape and structure? n are H bonds also between the functional groups?

the following factors contribute to the tertiary structure
-hydrogen bonding btwn R groups of amino acids
-ionic bonding btwn R groups of AA
-hydrophobic effect occurs
-the formation of disulfide bonds

u should get an ap bio review book..(assuming that u are taking ap bio rite now)
ok, thx ppl....i got it now....n im not takin ap bio....imma freshie^^
