Sort each peptide chain as part of a parallel %u03B2 sheet, part of an antiparallel %u03B2 sheet, either (cannot determine if parallel or antiparallel), or not part of a %u03B2 sheet (for example, if it is part of an %u03B1 helix). Be as specific as possible. For example, if a given structure is a parallel %u03B2 sheet, identify it as such.

Answer #1
Concepts and reason

Pauling and Corey proposed the secondary structure of a protein. Secondary structure of proteins has local structural conformations. There are different forms of a secondary structure of a protein. Secondary structure of a protein is formed by the repeating forms known as helix and beta sheets.

Fundamentals

In the secondary structure, the hydrogen bonds hold the folding back of the polypeptide chain that makes it appear side by side to form a beta sheet. Therefore, beta sheet is formed by the hydrogen bonding between the neighboring polypeptide strands. This occurs either parallel or antiparallel.

In parallel arrangement the polypeptide chains are in same direction. In anti-parallel beta arrangement, the polypeptide chains run in opposite direction.

The structure of parallel beta sheet is,

Parallel beta strand

The structure of anti-parallel beta sheet is,
