Which of the following is true?
A) The collagen helix and the a-helix are the only types of helices in proteins.
B) Globular proteins tend to be water soluble
C) Globular and fibrous are examples of secondary structure
D) All of these

Question

Quizplus · Accepted Answer

Globular proteins are typically soluble in water due to their hydrophilic amino acid residues being on the surface of the protein, which can interact with water molecules. The collagen helix and the a-helix are examples of secondary structure, but fibrous proteins specifically refer to proteins that have a long, narrow shape like fibers (e.g. keratin). Therefore, choice C is incorrect.
