WebIn antiparallel beta-sheets, one of the two possible H-bonded structures (containing 14 atoms in the H-bonded pseudoring) is energetically more favored and also more abundant in proteins than the other one (with 10 atoms involved in the pseudoring). WebSep 25, 2024 · This is not necessary for distant segments of a polypeptide chain to form beta-pleated sheets, but for proximal segments it is a definite requirement. For short distances, the two segments of a beta-pleated sheet are separated by 4+2n amino acid residues, with 4 being the minimum number of residues. α-PLEATED SHEETS

In this structure, two different regions of a polypeptide chain lie side by side and are bound by hydrogen bonds. They make up the core of many globular proteins. The two types of beta-pleated sheets are parallel beta-pleated sheets and antiparallel beta-pleated sheets.
