Question

Quizplus · Accepted Answer

A Ramachandran plot is a tool that displays the allowable conformations of amino acid residues in protein structures, based on steric constraints and hydrogen bonding. This information is particularly useful in understanding the spatial relationships between amino acid residues in secondary protein structure, such as alpha helices and beta sheets.
