The secondary structure of a protein is determined by
A)the amino acid composition.
B)the order of amino acids in the protein.
C)the hydrogen bonding between atoms in peptide bonds that gives the protein a three dimensional shape.
D)the intertwining of protein molecules to form a "functional" protein.

Question

Quizplus · Accepted Answer

The secondary structure of a protein is determined by the hydrogen bonding between atoms in peptide bonds that gives the protein a three-dimensional shape. This hydrogen bonding leads to the formation of alpha helices and beta sheets, which are the primary types of secondary structure. The amino acid composition and order also contribute to the overall structure, but they do not determine the specific secondary structure. The intertwining of protein molecules to form a functional protein is related to tertiary and quaternary structure, not secondary structure.
