Study Notes

Protein Folding Basics

A polypeptide lacks any stable three-dimensional structure during the primary structure stage.
The folding of many proteins begins during the translation of mRNA into a polypeptide chain.
The result of the interaction of amino acids during protein folding is a well-defined three-dimensional structure.
A polypeptide chain begins to fold into its three-dimensional structure as soon as it is synthesized.
The native three-dimensional structure of a protein is typically referred to as its native conformation.
Protein folding is the process by which a polypeptide chain takes on its native three-dimensional structure.
A polypeptide lacks any stable three-dimensional structure immediately after being translated from mRNA.
The folding of many proteins begins during translation, and the amino acids interact to produce a well-defined three-dimensional structure.
The initial state of a polypeptide after being translated from mRNA is a linear chain of amino acids with no stable three-dimensional structure.
