What is the key feature of tertiary protein structure?
Understand the Problem
The question is asking about the key features of tertiary protein structure, which relates to the three-dimensional arrangement of polypeptides in proteins.
Answer
It refers to the 3D folding of a single polypeptide.
The final answer is: It refers to the 3D folding of a single polypeptide.
Answer for screen readers
The final answer is: It refers to the 3D folding of a single polypeptide.
More Information
The tertiary structure represents the three-dimensional shape formed by the folding of a single polypeptide chain. It is stabilized by interactions between side chains of the amino acids.
Tips
Common mistake: Confusing tertiary structure with quaternary structure, which involves multiple polypeptide subunits.
