It is the distance where the atoms aren't repelling but are close enough to interact and cause a temporary dipole.
2 of 12
What side of the polypeptide do you count from?
n-terminus.
3 of 12
How do you confirm that an aa is in the L form
CORN rule.
4 of 12
How can you determine whether a protein is feasible?
Via the ramachandran plot using phi and psi angles. phi- N terminus psi - C terminus.
5 of 12
How long is the hydrogen bond?
0.28 nm.
6 of 12
What are physical features of the b-sheet?
Flexible and very high tensile strength (like spiders silk)
7 of 12
what is the b-turn?
Made up of 4 carbons, 1 hydrogen and 1 peptide bond.
8 of 12
What is the b-barrel, b-twist a-helix bundle and rosmand fold?
8-strands that for, a flexible barrel structure. 2. twist of strands 3. barrels come together 4 at a time and rosmandfolds consit of 6 b-sheets and alpha helixes.
9 of 12
What is a collagen triple helix?
three chains with h-bonds between then. 3 residues per turn. it is a left handed helix in each chain but the super helix is right handed. It has a sequence gly-x-y-gly. x and y are mainly proline.
10 of 12
Wha is an alpha helix?
H-bonds within the chain. 0.54 nm per turn. 3.6 residues per turn. right handed helix. no proline
11 of 12
What are the two structures used for transmembrane proteins?
Alpha bundles and b-barrels.
