WebJul 4, 2024 · Secondary Structure: β-Pleated Sheet. This structure occurs when two (or more, e.g. ψ-loop) segments of a polypeptide chain overlap one another and form a row of hydrogen bonds with each other. This can happen in a parallel arrangement: Parallel and anti-parallel arrangement is the direct consequence of the directionality of the polypeptide ... WebApr 9, 2024 · Figure 19.1. 2: Peptide Bonds. A peptide bond forms when the amino group of one amino acid bonds to the carboxyl group of another amino acid. A peptide is two or more amino acids joined together by peptide bonds, and a polypeptide is a chain of many amino acids. A protein contains one or more polypeptides. Therefore, proteins are long …
