Detailed explanation-1: -The primary structure of a protein-its amino acid sequence-drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein’s unique three-dimensional shape.
Detailed explanation-2: -There are four stages of protein folding, primary, secondary, tertiary and quarternary.
Detailed explanation-3: -When folding, two types of structures usually form first. Some regions of the protein chain coil up into slinky-like formations called “alpha helices, ” while other regions fold into zigzag patterns called “beta sheets, ” which resemble the folds of a paper fan.
Detailed explanation-4: -Proteins fold into stable three‐dimensional shapes, or conformations, that are determined by their amino acid sequence. The complete structure of a protein can be described at four different levels of complexity: primary, secondary, tertiary, and quaternary structure.
