Question

The β-strands can run in both parallel and antiparallel direction. Please explain this phenomenon. Write about number of secondary structure of any protein of your interest?

Answer 1

Answer:

 β strands are usually depicted by broad arrows pointing in the direction of the carboxyl-terminal end to indicate the type of β sheet formed—parallel or antiparallel. More structurally diverse than α helices, β sheets can be relatively flat but most adopt a somewhat twisted shape. The β sheet is an important structural element in many proteins. For example, fatty acid-binding proteins, important for lipid metabolism, are built almost entirely from β sheets.
