Answer:
a) The minimum number of residues in alfa helix to span 30 Å, is 20 residues
b) The minimum number of residues in a Beta sheet to span 30 Å, is 8.6 residues.
c) Should be better if you show an image to do this question.
d) Look answer below.
Explanation:
a) Due to every 5,4 Å there are 3,6 residues. So doing the calculus give us 20 residues.
b) That’s it because every 7 Å there are 2 residues
c) First of all, is important to know that the residues of a protein define the secondary structure due to intermolecular and intramolecular interactions. Taking in account that the membrane bilayer has a lipid interior α-helical domains which are hydrophobic principally are embedded in membranes by hydrophobic interactions with the lipid interior of the bilayer favored by Van der Waals interactions and probably also by ionic interactions with the polar head groups of the phospholipids.
not sure.. you should eat poptarts
Answer:
The structure is shown in the figure.
Explanation:
There is condensation polymersiation in case of lactic acid with the removal of water molecule (dehydration) leading to formation of poly lactic acid.
The structure of PLA is shown in the figure.
<span>Answer:
Q = 500.0 x 4.18 x 8.63 = 18037 J => 18.037 kJ
moles anthracene = 0.455 g/ 178.234 g/mol=0.00255
0.00255 moles give 18.037 kJ
0.00255 : 18.037 = 1 mole : x
x = 7073 kJ/mol
enthalpy = - 70.73 kJ/mol</span>
