Question

Quizplus · Accepted Answer

A pleated sheet is an example of a secondary structure of a protein. It is formed by hydrogen bonds between nearby chains of amino acids, allowing for a stabilized, repetitive structure. Alpha amino acids, peptide linkages, and serine are all individual components of proteins but do not represent a secondary structure on their own.
