Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following occurs first when folding a disordered polypeptide chain into a stable protein formation?
A
formation of a low energy state
B
association of ordered subunits
C
aggregation of hydrophobic regions in the protein
D
tertiary structure refinement
E
formation of a low entropy state
Explanation: 

Detailed explanation-1: -Formation of secondary structural element which are alpha helices and beta sheets is the first step in the folding of disordered polypeptide chains into stable protein. Peptide bonds are linked together to form polypeptide.

Detailed explanation-2: -Protein folding is a process by which a polypeptide chain folds to become a biologically active protein in its native 3D structure. Protein structure is crucial to its function. Folded proteins are held together by various molecular interactions.

Detailed explanation-3: -Proteins fold into stable three‚Äźdimensional 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.

Detailed explanation-4: -Primary Structure. Secondary Structure. Tertiary Structure. Quaternary Structure.
