The primary 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 that gives the protein three dimensional shape.
D)the intertwining of protein molecules to form a "functional" protein.

Question

Quizplus · Accepted Answer

The primary structure of a protein refers to the linear sequence of amino acids in the polypeptide chain. This sequence is determined by the genetic code, which specifies the order of amino acids in the protein. The amino acid composition of a protein can vary, but the order of amino acids is specific to each protein and determines its unique structure and function. Hydrogen bonding and intertwining of protein molecules occur at higher levels of protein structure, such as secondary, tertiary, and quaternary structures.
