Question

Beta (β) sheets are a type of secondary structure in proteins. A segment of a single chain in an antiparallel β sheet has a length of 80.5 Å . How many residues are in this segment?

Answer 1

Step-by-step explanation:

The structural repeating unit of beta sheet is 7 anstrom/2 aminoacids. So,

`(80.5 Angstrom)/(3.5) = 23 aminoacids`

If a segment of a single chain in an antiparallel beta sheet has a length of 80.5 angstrom, then there will be 23 residues in this segment.
