The linear sequence of the components of amino acids is referred to as which type of
structure?
a. Primary
b. Secondary
c. Tertiary
d. Quaternary - Correct Answer A. The linear sequence of the components of amino acids is
referred to as primary structure.
B. Secondary structure is a steric interaction of amino acids that close to one another in the
linear sequence. Alpha helix and beta helix are examples.
C. Tertiary structure is a steric interaction between amino acids that are far apart in the linear
sequence which causes folding and the ultimate functional structure of the protein. Disulfide
bonds are an example.
D. Quaternary structure is the steric interaction between subunits of proteins with more than
one polypeptide chain. Hemoglobin is an example
