An alpha-helix of 40 Angstrom will have ___ residues. Please show your calculations.
a. 11
b. 26
c. 7
d. 19
Answer: An alpha-helix of 40 Angstrom will have 26 residues. Please show your calculations.
In an alpha helix, 1 amino acid residue takes 1.5-angstrom distance.
For 40 Angstrom, The number of amino acids = 40/1.5 = 26.7 i.e. around 26 residues.

I have a 44 angstrom section of alpha-keratin. How many residues would be required to span this distance? HINT: Number of turns of a helix of keratin and number of residues/turn. a. 18 b. 23 c. 27 d. 30
What is the length of an a-helix made of 40 residues? 27 angstroms 60 angstroms 11 angstroms 216 angstroms
22. Consider an alpha helix with sequence VLADWMAVELA, and consider the hydrogen bonds that are required in order to form the alpha helix. A. Fill in all of the hydrogen bonds that must form between a given residue's backbone N-H backbone C-O, or R group, indicating what the hydrogen bonding partner for each will be. For example, the C-O of V1 is a hydrogen bond acceptor of the W5 N-H hydrogen bond donor, reflected in the appropriate squares under V1...

Understand alpha helices and beta pleated sheets Question How is it possible for the a-helix to have amino acids with bulky side chains while the B-pleated sheets cannot? Select the correct answer below: O The R groups in the a-helix stabilize the structure, while they interfere with the hydrogen bonds in a B-pleated sheet. The R groups are contained inside the a-helix structure, while they interfere with the hydrogen bonds in a B- pleated sheet. O The R groups lie...
