Match the following letters and numbers a Betapleated sheet

Match the following letters and numbers:

a) Beta-pleated sheet

b) Beta Strand

c) Secondary Structure

1) Fully extended polypeptide chain

2) Formed by hydrogen bonds between parallel or anti parallel chain

3) Regular repeating three-dimensional structures

Solution

1-b: A beta strand is a stretch of about 3-10 amino acids with backbone in an extended conformation

2-a: Beta-pleats are formed by hydrogen bonds between parallel or anti parallel beta strands.

3-c: Secondary structures, such as alpha-helix or beta pleated sheets, consist of regularly repeating three-dimensional structures.
